Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516732, here are decompositions:

3 + 31516729 = 31516732
29 + 31516703 = 31516732
101 + 31516631 = 31516732
113 + 31516619 = 31516732
173 + 31516559 = 31516732
239 + 31516493 = 31516732
263 + 31516469 = 31516732
353 + 31516379 = 31516732

Showing the first eight; more decompositions exist.
