Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631630, here are decompositions:

13 + 8631617 = 8631630
19 + 8631611 = 8631630
31 + 8631599 = 8631630
61 + 8631569 = 8631630
97 + 8631533 = 8631630
113 + 8631517 = 8631630
131 + 8631499 = 8631630
151 + 8631479 = 8631630

Showing the first eight; more decompositions exist.
