Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530926, here are decompositions:

127 + 31530799 = 31530926
223 + 31530703 = 31530926
277 + 31530649 = 31530926
283 + 31530643 = 31530926
337 + 31530589 = 31530926
439 + 31530487 = 31530926
577 + 31530349 = 31530926
829 + 31530097 = 31530926

Showing the first eight; more decompositions exist.
