Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615658, here are decompositions:

5 + 8615653 = 8615658
67 + 8615591 = 8615658
71 + 8615587 = 8615658
131 + 8615527 = 8615658
151 + 8615507 = 8615658
167 + 8615491 = 8615658
179 + 8615479 = 8615658
197 + 8615461 = 8615658

Showing the first eight; more decompositions exist.
