Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613462, here are decompositions:

61 + 31613401 = 31613462
79 + 31613383 = 31613462
271 + 31613191 = 31613462
409 + 31613053 = 31613462
523 + 31612939 = 31613462
571 + 31612891 = 31613462
631 + 31612831 = 31613462
709 + 31612753 = 31613462

Showing the first eight; more decompositions exist.
