Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631790, here are decompositions:

3 + 8631787 = 8631790
47 + 8631743 = 8631790
53 + 8631737 = 8631790
131 + 8631659 = 8631790
173 + 8631617 = 8631790
179 + 8631611 = 8631790
191 + 8631599 = 8631790
257 + 8631533 = 8631790

Showing the first eight; more decompositions exist.
