Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631768, here are decompositions:

31 + 8631737 = 8631768
109 + 8631659 = 8631768
139 + 8631629 = 8631768
151 + 8631617 = 8631768
157 + 8631611 = 8631768
199 + 8631569 = 8631768
251 + 8631517 = 8631768
269 + 8631499 = 8631768

Showing the first eight; more decompositions exist.
