Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631228, here are decompositions:

29 + 8631199 = 8631228
37 + 8631191 = 8631228
61 + 8631167 = 8631228
131 + 8631097 = 8631228
191 + 8631037 = 8631228
211 + 8631017 = 8631228
227 + 8631001 = 8631228
257 + 8630971 = 8631228

Showing the first eight; more decompositions exist.
