Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656732, here are decompositions:

3 + 8656729 = 8656732
5 + 8656727 = 8656732
11 + 8656721 = 8656732
41 + 8656691 = 8656732
233 + 8656499 = 8656732
239 + 8656493 = 8656732
251 + 8656481 = 8656732
263 + 8656469 = 8656732

Showing the first eight; more decompositions exist.
