Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631238, here are decompositions:

47 + 8631191 = 8631238
71 + 8631167 = 8631238
197 + 8631041 = 8631238
227 + 8631011 = 8631238
401 + 8630837 = 8631238
449 + 8630789 = 8631238
467 + 8630771 = 8631238
479 + 8630759 = 8631238

Showing the first eight; more decompositions exist.
