Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631944, here are decompositions:

37 + 8631907 = 8631944
157 + 8631787 = 8631944
163 + 8631781 = 8631944
271 + 8631673 = 8631944
571 + 8631373 = 8631944
577 + 8631367 = 8631944
613 + 8631331 = 8631944
661 + 8631283 = 8631944

Showing the first eight; more decompositions exist.
