Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631836, here are decompositions:

13 + 8631823 = 8631836
67 + 8631769 = 8631836
163 + 8631673 = 8631836
337 + 8631499 = 8631836
457 + 8631379 = 8631836
463 + 8631373 = 8631836
607 + 8631229 = 8631836
643 + 8631193 = 8631836

Showing the first eight; more decompositions exist.
