Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530762, here are decompositions:

59 + 31530703 = 31530762
61 + 31530701 = 31530762
79 + 31530683 = 31530762
83 + 31530679 = 31530762
101 + 31530661 = 31530762
103 + 31530659 = 31530762
113 + 31530649 = 31530762
173 + 31530589 = 31530762

Showing the first eight; more decompositions exist.
