Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631616, here are decompositions:

5 + 8631611 = 8631616
17 + 8631599 = 8631616
47 + 8631569 = 8631616
83 + 8631533 = 8631616
137 + 8631479 = 8631616
347 + 8631269 = 8631616
449 + 8631167 = 8631616
593 + 8631023 = 8631616

Showing the first eight; more decompositions exist.
