Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613924, here are decompositions:

127 + 31613797 = 31613924
373 + 31613551 = 31613924
487 + 31613437 = 31613924
523 + 31613401 = 31613924
541 + 31613383 = 31613924
547 + 31613377 = 31613924
733 + 31613191 = 31613924
787 + 31613137 = 31613924

Showing the first eight; more decompositions exist.
