Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657656, here are decompositions:

5 + 8657651 = 8657656
17 + 8657639 = 8657656
23 + 8657633 = 8657656
89 + 8657567 = 8657656
233 + 8657423 = 8657656
269 + 8657387 = 8657656
347 + 8657309 = 8657656
419 + 8657237 = 8657656

Showing the first eight; more decompositions exist.
