Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631938, here are decompositions:

31 + 8631907 = 8631938
151 + 8631787 = 8631938
157 + 8631781 = 8631938
421 + 8631517 = 8631938
439 + 8631499 = 8631938
487 + 8631451 = 8631938
547 + 8631391 = 8631938
571 + 8631367 = 8631938

Showing the first eight; more decompositions exist.
