Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10658, here are decompositions:

7 + 10651 = 10658
19 + 10639 = 10658
31 + 10627 = 10658
61 + 10597 = 10658
127 + 10531 = 10658
157 + 10501 = 10658
181 + 10477 = 10658
199 + 10459 = 10658

Showing the first eight; more decompositions exist.
