Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516632, here are decompositions:

5 + 31516627 = 31516632
13 + 31516619 = 31516632
19 + 31516613 = 31516632
29 + 31516603 = 31516632
61 + 31516571 = 31516632
73 + 31516559 = 31516632
89 + 31516543 = 31516632
109 + 31516523 = 31516632

Showing the first eight; more decompositions exist.
