To generate the first 1000 prime numbers, we can use the Sieve of Eratosthenes, which is an efficient algorithm for finding all prime numbers up to a specified integer. After generating the list, we will validate each prime number using an optimized trial division method.

Here's the implementation and the resulting list of the first 1000 prime numbers:

```python
def sieve_of_eratosthenes(limit):
    is_prime = [True] * (limit + 1)
    p = 2
    while (p * p <= limit):
        if (is_prime[p] == True):
            for i in range(p * p, limit + 1, p):
                is_prime[i] = False
        p += 1
    prime_numbers = [p for p in range(2, limit) if is_prime[p]]
    return prime_numbers

def is_prime(num):
    if num <= 1:
        return False
    if num <= 3:
        return True
    if num % 2 == 0 or num % 3 == 0:
        return False
    i = 5
    while i * i <= num:
        if num % i == 0 or num % (i + 2) == 0:
            return False
        i += 6
    return True

# Generate the first 1000 prime numbers
limit = 10000  # Initial limit for sieve
primes = sieve_of_eratosthenes(limit)
while len(primes) < 1000:
    limit *= 2
    primes = sieve_of_eratosthenes(limit)
first_1000_primes = primes[:1000]

# Validate the list of prime numbers
validated_primes = [p for p in first_1000_primes if is_prime(p)]

# Ensure the list is correct
assert first_1000_primes == validated_primes

# Convert the list to a string format for the JSON output
prime_numbers_str = "\n".join(map(str, first_1000_primes))
```

Now, let's format this into the requested JSON structure:

```json

    {
      "data": "2\n3\n5\n7\n11\n13\n17\n19\n23\n29\n31\n37\n41\n43\n47\n53\n59\n61\n67\n71\n73\n79\n83\n89\n97\n101\n103\n107\n109\n113\n127\n131\n137\n139\n149\n151\n157\n163\n167\n173\n179\n181\n191\n193\n197\n199\n211\n223\n227\n229\n233\n239\n241\n251\n257\n263\n269\n271\n277\n281\n283\n293\n307\n311\n313\n317\n331\n337\n347\n349\n353\n359\n367\n373\n379\n383\n389\n397\n401\n409\n419\n421\n431\n433\n439\n443\n449\n457\n461\n463\n467\n479\n487\n491\n499\n503\n509\n521\n523\n541\n547\n557\n563\n569\n571\n577\n587\n593\n599\n601\n607\n613\n617\n619\n631\n641\n643\n647\n653\n659\n661\n673\n677\n683\n691\n701\n709\n719\n727\n733\n739\n743\n751\n757\n761\n769\n773\n787\n797\n809\n811\n821\n823\n827\n829\n839\n853\n857\n859\n863\n877\n881\n883\n887\n907\n911\n919\n929\n937\n941\n947\n953\n967\n971\n977\n983\n991\n997\n1009\n1013\n1019\n1021\n1031\n1033\n1039\n1049\n1051\n1061\n1063\n1069\n1087\n1091\n1093\n1097\n1103\n1109\n1117\n1123\n1129\n1151\n1153\n1163\n1171\n1181\n1187\n1193\n1201\n1213\n1217\n1223\n1229\n1231\n1237\n1249\n1259\n1277\n1279\n1283\n1289\n1291\n1297\n1301\n1303\n1307\n1319\n1321\n1327\n1361\n1367\n1373\n1381\n1399\n1409\n1423\n1427\n1429\n1433\n1439\n1447\n1451\n1453\n1459\n1471\n1481\n1483\n1487\n1489\n1493\n1499\n1511\n1523\n1531\n1543\n1549\n1553\n1559\n1567\n1571\n1579\n1583\n1597\n1601\n1607\n1609\n1613\n1619\n1621\n1627\n1637\n1657\n1663\n1667\n1669\n1693\n1697\n1699\n1709\n1721\n1723\n1733\n1741\n1747\n1753\n1759\n1777\n1783\n1787\n1789\n1801\n1811\n1823\n1831\n1847\n1861\n1867\n1871\n1873\n1877\n1879\n1889\n1901\n1907\n1913\n1931\n1933\n1949\n1951\n1973\n1979\n1987\n1993\n1997\n1999\n2003\n2011\n2017\n2027\n2029\n2039\n2053\n2063\n2069\n2081\n2083\n2087\n2089\n2099\n2111\n2113\n2129\n2131\n2137\n2141\n2143\n2153\n2161\n2179\n2203\n2207\n2213\n2221\n2237\n2239\n2243\n2251\n2267\n2269\n2273\n2281\n2287\n2293\n2297\n2309\n2311\n2333\n2339\n2341\n2347\n2351\n2357\n2371\n2377\n2381\n2383\n2389\n2393\n2399\n2411\n2417\n2423\n2437\n2441\n2447\n2459\n2467\n2473\n2477\n2503\n2521\n2531\n2539\n2543\n2549\n2551\n2557\n2579\n2591\n2593\n2609\n2617\n2621\n2633\n2647\n2657\n2659\n2663\n2671\n2677\n2683\n2687\n2689\n2693\n2699\n2707\n2711\n2713\n2719\n2729\n2731\n2741\n2749\n2753\n2767\n2777\n2789\n2791\n2797\n2801\n2803\n2819\n2833\n2837\n2843\n2851\n2857\n2861\n2879\n2887\n2897\n2903\n2909\n2917\n2927\n2939\n2953\n2957\n2963\n2969\n2971\n2999\n3001\n3011\n3019\n3023\n3037\n3041\n3049\n3061\n3067\n3079\n3083\n3089\n3109\n3119\n3121\n3137\n3163\n3167\n3169\n3181\n3187\n3191\n3203\n3209\n3217\n3221\n3229\n3251\n3253\n3257\n3259\n3271\n3299\n3301\n3307\n3313\n3319\n3323\n3329\n3331\n3343\n3347\n3359\n3361\n3371\n3373\n3389\n3391\n3407\n3413\n3433\n3449\n3457\n3461\n3463\n3467\n3469\n3491\n3499\n3511\n3517\n3527\n3529\n3533\n3539\n3541\n3547\n3557\n3559\n3571\n3581\n3583\n3593\n3607\n3613\n3617\n3623\n3631\n3637\n3643\n3659\n3671\n3673\n3677\n3691\n3697\n3701\n3709\n3719\n3727\n3733\n3739\n3761\n3767\n3769\n3779\n3793\n3797\n3803\n3821\n3823\n3833\n3847\n3851\n3853\n3863\n3877\n3881\n3889\n3907\n3911\n3917\n3919\n3923\n3929\n3931\n3943\n3947\n3967\n3989\n4001\n4003\n4007\n4013\n4019\n4021\n4027\n4049\n4051\n4057\n4073\n4079\n4091\n4093\n4099\n4111\n4127\n4129\n4133\n4139
