Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631798, here are decompositions:

11 + 8631787 = 8631798
17 + 8631781 = 8631798
29 + 8631769 = 8631798
61 + 8631737 = 8631798
139 + 8631659 = 8631798
181 + 8631617 = 8631798
199 + 8631599 = 8631798
229 + 8631569 = 8631798

Showing the first eight; more decompositions exist.
