Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631866, here are decompositions:

43 + 8631823 = 8631866
79 + 8631787 = 8631866
97 + 8631769 = 8631866
193 + 8631673 = 8631866
349 + 8631517 = 8631866
367 + 8631499 = 8631866
487 + 8631379 = 8631866
499 + 8631367 = 8631866

Showing the first eight; more decompositions exist.
