Nonnegative values·of solutions (x, y) to the Diophantine equation x² + (x + 47²)² = y². A332000

For positive n with prime decomposition n = ∏_j=1..m (p_j^k_j) define A_n = ∑_j=1..m (p_j*k_j) and B_n = ∑_j=1..m (p_j^k_j). This sequence gives those n for which A_n and B_n are both prime and B_n = A_n + 2 (i.e., form a twin prime pair). A185718
