Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624886, here are decompositions:

37 + 31624849 = 31624886
79 + 31624807 = 31624886
103 + 31624783 = 31624886
379 + 31624507 = 31624886
409 + 31624477 = 31624886
457 + 31624429 = 31624886
463 + 31624423 = 31624886
499 + 31624387 = 31624886

Showing the first eight; more decompositions exist.
