Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530738, here are decompositions:

37 + 31530701 = 31530738
59 + 31530679 = 31530738
79 + 31530659 = 31530738
89 + 31530649 = 31530738
97 + 31530641 = 31530738
101 + 31530637 = 31530738
131 + 31530607 = 31530738
149 + 31530589 = 31530738

Showing the first eight; more decompositions exist.
