Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631422, here are decompositions:

31 + 8631391 = 8631422
43 + 8631379 = 8631422
103 + 8631319 = 8631422
139 + 8631283 = 8631422
193 + 8631229 = 8631422
223 + 8631199 = 8631422
229 + 8631193 = 8631422
271 + 8631151 = 8631422

Showing the first eight; more decompositions exist.
