Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8600656, here are decompositions:

17 + 8600639 = 8600656
23 + 8600633 = 8600656
107 + 8600549 = 8600656
137 + 8600519 = 8600656
179 + 8600477 = 8600656
257 + 8600399 = 8600656
263 + 8600393 = 8600656
347 + 8600309 = 8600656

Showing the first eight; more decompositions exist.
