Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631806, here are decompositions:

3 + 8631803 = 8631806
19 + 8631787 = 8631806
37 + 8631769 = 8631806
307 + 8631499 = 8631806
433 + 8631373 = 8631806
439 + 8631367 = 8631806
487 + 8631319 = 8631806
499 + 8631307 = 8631806

Showing the first eight; more decompositions exist.
