Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656458, here are decompositions:

47 + 8656411 = 8656458
59 + 8656399 = 8656458
79 + 8656379 = 8656458
89 + 8656369 = 8656458
101 + 8656357 = 8656458
137 + 8656321 = 8656458
179 + 8656279 = 8656458
227 + 8656231 = 8656458

Showing the first eight; more decompositions exist.
