Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631746, here are decompositions:

3 + 8631743 = 8631746
73 + 8631673 = 8631746
229 + 8631517 = 8631746
367 + 8631379 = 8631746
373 + 8631373 = 8631746
379 + 8631367 = 8631746
439 + 8631307 = 8631746
463 + 8631283 = 8631746

Showing the first eight; more decompositions exist.
