Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516996, here are decompositions:

3 + 31516993 = 31516996
23 + 31516973 = 31516996
107 + 31516889 = 31516996
239 + 31516757 = 31516996
293 + 31516703 = 31516996
383 + 31516613 = 31516996
503 + 31516493 = 31516996
569 + 31516427 = 31516996

Showing the first eight; more decompositions exist.
