Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656918, here are decompositions:

47 + 8656871 = 8656918
71 + 8656847 = 8656918
89 + 8656829 = 8656918
131 + 8656787 = 8656918
191 + 8656727 = 8656918
197 + 8656721 = 8656918
227 + 8656691 = 8656918
251 + 8656667 = 8656918

Showing the first eight; more decompositions exist.
