Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656966, here are decompositions:

47 + 8656919 = 8656966
137 + 8656829 = 8656966
179 + 8656787 = 8656966
233 + 8656733 = 8656966
239 + 8656727 = 8656966
389 + 8656577 = 8656966
419 + 8656547 = 8656966
443 + 8656523 = 8656966

Showing the first eight; more decompositions exist.
