Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516716, here are decompositions:

13 + 31516703 = 31516716
17 + 31516699 = 31516716
19 + 31516697 = 31516716
47 + 31516669 = 31516716
83 + 31516633 = 31516716
89 + 31516627 = 31516716
97 + 31516619 = 31516716
103 + 31516613 = 31516716

Showing the first eight; more decompositions exist.
