Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549076, here are decompositions:

37 + 31549039 = 31549076
67 + 31549009 = 31549076
79 + 31548997 = 31549076
313 + 31548763 = 31549076
337 + 31548739 = 31549076
379 + 31548697 = 31549076
457 + 31548619 = 31549076
463 + 31548613 = 31549076

Showing the first eight; more decompositions exist.
