Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631786, here are decompositions:

5 + 8631781 = 8631786
17 + 8631769 = 8631786
43 + 8631743 = 8631786
73 + 8631713 = 8631786
113 + 8631673 = 8631786
127 + 8631659 = 8631786
157 + 8631629 = 8631786
269 + 8631517 = 8631786

Showing the first eight; more decompositions exist.
