Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631448, here are decompositions:

47 + 8631401 = 8631448
107 + 8631341 = 8631448
179 + 8631269 = 8631448
197 + 8631251 = 8631448
257 + 8631191 = 8631448
281 + 8631167 = 8631448
431 + 8631017 = 8631448
587 + 8630861 = 8631448

Showing the first eight; more decompositions exist.
