Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530626, here are decompositions:

19 + 31530607 = 31530626
37 + 31530589 = 31530626
103 + 31530523 = 31530626
139 + 31530487 = 31530626
277 + 31530349 = 31530626
727 + 31529899 = 31530626
877 + 31529749 = 31530626
997 + 31529629 = 31530626

Showing the first eight; more decompositions exist.
