Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631732, here are decompositions:

19 + 8631713 = 8631732
59 + 8631673 = 8631732
73 + 8631659 = 8631732
103 + 8631629 = 8631732
163 + 8631569 = 8631732
199 + 8631533 = 8631732
233 + 8631499 = 8631732
281 + 8631451 = 8631732

Showing the first eight; more decompositions exist.
