Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631816, here are decompositions:

13 + 8631803 = 8631816
29 + 8631787 = 8631816
47 + 8631769 = 8631816
73 + 8631743 = 8631816
79 + 8631737 = 8631816
103 + 8631713 = 8631816
157 + 8631659 = 8631816
199 + 8631617 = 8631816

Showing the first eight; more decompositions exist.
