Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657188, here are decompositions:

167 + 8657021 = 8657188
179 + 8657009 = 8657188
269 + 8656919 = 8657188
317 + 8656871 = 8657188
359 + 8656829 = 8657188
401 + 8656787 = 8657188
461 + 8656727 = 8657188
467 + 8656721 = 8657188

Showing the first eight; more decompositions exist.
