Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631478, here are decompositions:

137 + 8631341 = 8631478
227 + 8631251 = 8631478
311 + 8631167 = 8631478
461 + 8631017 = 8631478
467 + 8631011 = 8631478
617 + 8630861 = 8631478
641 + 8630837 = 8631478
719 + 8630759 = 8631478

Showing the first eight; more decompositions exist.
