Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613798, here are decompositions:

79 + 31613719 = 31613798
397 + 31613401 = 31613798
421 + 31613377 = 31613798
457 + 31613341 = 31613798
571 + 31613227 = 31613798
607 + 31613191 = 31613798
661 + 31613137 = 31613798
691 + 31613107 = 31613798

Showing the first eight; more decompositions exist.
