Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631766, here are decompositions:

23 + 8631743 = 8631766
29 + 8631737 = 8631766
53 + 8631713 = 8631766
107 + 8631659 = 8631766
137 + 8631629 = 8631766
149 + 8631617 = 8631766
167 + 8631599 = 8631766
197 + 8631569 = 8631766

Showing the first eight; more decompositions exist.
