Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651224, here are decompositions:

17 + 8651207 = 8651224
83 + 8651141 = 8651224
107 + 8651117 = 8651224
173 + 8651051 = 8651224
227 + 8650997 = 8651224
431 + 8650793 = 8651224
503 + 8650721 = 8651224
521 + 8650703 = 8651224

Showing the first eight; more decompositions exist.
