Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631436, here are decompositions:

167 + 8631269 = 8631436
269 + 8631167 = 8631436
353 + 8631083 = 8631436
419 + 8631017 = 8631436
599 + 8630837 = 8631436
647 + 8630789 = 8631436
677 + 8630759 = 8631436
773 + 8630663 = 8631436

Showing the first eight; more decompositions exist.
