Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631772, here are decompositions:

3 + 8631769 = 8631772
29 + 8631743 = 8631772
59 + 8631713 = 8631772
113 + 8631659 = 8631772
173 + 8631599 = 8631772
239 + 8631533 = 8631772
293 + 8631479 = 8631772
431 + 8631341 = 8631772

Showing the first eight; more decompositions exist.
