Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101658, here are decompositions:

5 + 101653 = 101658
17 + 101641 = 101658
31 + 101627 = 101658
47 + 101611 = 101658
59 + 101599 = 101658
97 + 101561 = 101658
127 + 101531 = 101658
131 + 101527 = 101658

Showing the first eight; more decompositions exist.
