Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631916, here are decompositions:

5 + 8631911 = 8631916
17 + 8631899 = 8631916
23 + 8631893 = 8631916
113 + 8631803 = 8631916
173 + 8631743 = 8631916
179 + 8631737 = 8631916
257 + 8631659 = 8631916
317 + 8631599 = 8631916

Showing the first eight; more decompositions exist.
