Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516734, here are decompositions:

5 + 31516729 = 31516734
31 + 31516703 = 31516734
37 + 31516697 = 31516734
101 + 31516633 = 31516734
103 + 31516631 = 31516734
107 + 31516627 = 31516734
131 + 31516603 = 31516734
163 + 31516571 = 31516734

Showing the first eight; more decompositions exist.
