Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631494, here are decompositions:

43 + 8631451 = 8631494
103 + 8631391 = 8631494
127 + 8631367 = 8631494
163 + 8631331 = 8631494
211 + 8631283 = 8631494
397 + 8631097 = 8631494
457 + 8631037 = 8631494
523 + 8630971 = 8631494

Showing the first eight; more decompositions exist.
