Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530692, here are decompositions:

13 + 31530679 = 31530692
31 + 31530661 = 31530692
43 + 31530649 = 31530692
103 + 31530589 = 31530692
241 + 31530451 = 31530692
283 + 31530409 = 31530692
631 + 31530061 = 31530692
691 + 31530001 = 31530692

Showing the first eight; more decompositions exist.
