Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631760, here are decompositions:

17 + 8631743 = 8631760
23 + 8631737 = 8631760
47 + 8631713 = 8631760
101 + 8631659 = 8631760
131 + 8631629 = 8631760
149 + 8631611 = 8631760
191 + 8631569 = 8631760
227 + 8631533 = 8631760

Showing the first eight; more decompositions exist.
