Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631974, here are decompositions:

31 + 8631943 = 8631974
67 + 8631907 = 8631974
151 + 8631823 = 8631974
193 + 8631781 = 8631974
457 + 8631517 = 8631974
523 + 8631451 = 8631974
601 + 8631373 = 8631974
607 + 8631367 = 8631974

Showing the first eight; more decompositions exist.
