Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634228, here are decompositions:

17 + 8634211 = 8634228
59 + 8634169 = 8634228
67 + 8634161 = 8634228
89 + 8634139 = 8634228
151 + 8634077 = 8634228
179 + 8634049 = 8634228
257 + 8633971 = 8634228
269 + 8633959 = 8634228

Showing the first eight; more decompositions exist.
