Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631670, here are decompositions:

11 + 8631659 = 8631670
41 + 8631629 = 8631670
53 + 8631617 = 8631670
59 + 8631611 = 8631670
71 + 8631599 = 8631670
101 + 8631569 = 8631670
137 + 8631533 = 8631670
191 + 8631479 = 8631670

Showing the first eight; more decompositions exist.
