Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516764, here are decompositions:

7 + 31516757 = 31516764
11 + 31516753 = 31516764
61 + 31516703 = 31516764
67 + 31516697 = 31516764
131 + 31516633 = 31516764
137 + 31516627 = 31516764
151 + 31516613 = 31516764
193 + 31516571 = 31516764

Showing the first eight; more decompositions exist.
