Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631730, here are decompositions:

17 + 8631713 = 8631730
71 + 8631659 = 8631730
101 + 8631629 = 8631730
113 + 8631617 = 8631730
131 + 8631599 = 8631730
197 + 8631533 = 8631730
251 + 8631479 = 8631730
389 + 8631341 = 8631730

Showing the first eight; more decompositions exist.
