Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516936, here are decompositions:

47 + 31516889 = 31516936
149 + 31516787 = 31516936
179 + 31516757 = 31516936
233 + 31516703 = 31516936
239 + 31516697 = 31516936
317 + 31516619 = 31516936
443 + 31516493 = 31516936
467 + 31516469 = 31516936

Showing the first eight; more decompositions exist.
