Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613996, here are decompositions:

157 + 31613839 = 31613996
163 + 31613833 = 31613996
199 + 31613797 = 31613996
277 + 31613719 = 31613996
367 + 31613629 = 31613996
373 + 31613623 = 31613996
457 + 31613539 = 31613996
613 + 31613383 = 31613996

Showing the first eight; more decompositions exist.
