Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656786, here are decompositions:

53 + 8656733 = 8656786
59 + 8656727 = 8656786
197 + 8656589 = 8656786
239 + 8656547 = 8656786
263 + 8656523 = 8656786
269 + 8656517 = 8656786
293 + 8656493 = 8656786
317 + 8656469 = 8656786

Showing the first eight; more decompositions exist.
