Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516674, here are decompositions:

5 + 31516669 = 31516674
41 + 31516633 = 31516674
43 + 31516631 = 31516674
47 + 31516627 = 31516674
61 + 31516613 = 31516674
71 + 31516603 = 31516674
103 + 31516571 = 31516674
107 + 31516567 = 31516674

Showing the first eight; more decompositions exist.
