Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631756, here are decompositions:

13 + 8631743 = 8631756
19 + 8631737 = 8631756
43 + 8631713 = 8631756
83 + 8631673 = 8631756
97 + 8631659 = 8631756
127 + 8631629 = 8631756
139 + 8631617 = 8631756
157 + 8631599 = 8631756

Showing the first eight; more decompositions exist.
