We present an exhaustive computational study of prime values generated by the high-degree difference polynomial Q (n) = n⁴7 - (n-1) ⁴7 over the range 1 ≤ n ≤ 3×10⁸, identifying 2, 597, 698 prime values ranging from 53 to 392 digits. Key Results: - Hardy-Littlewood Verification: We discovered exactly 3 prime quadruplets (consecutive 4-tuples where Q (n), Q (n+1), Q (n+2), Q (n+3) are all prime), occurring at n = 117, 309, 848, 136, 584, 738, and 218, 787, 064. This matches the Hardy-Littlewood theoretical prediction of 3. 52 with remarkable precision (ratio 0. 85). - Small-Prime Immunity Theorem: We prove that for all primes p < 283 with p ≢ 1 (mod 47), the polynomial Q (n) is never divisible by p. This is computationally verified through residue analysis modulo 283, confirming that all 46 forbidden residue classes contain exactly zero prime-producing values. - Bateman-Horn Consistency: The observed density decay from ~25, 000 primes per million (at n ~ 10³) to ~9, 800 primes per million (at n ~ 3×10⁸) follows the Bateman-Horn prediction across six orders of magnitude. Dataset includes complete list of 2, 597, 698 prime-producing n values, all k-tuple locations, LaTeX source, and high-resolution figures.
