Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516692, here are decompositions:

23 + 31516669 = 31516692
59 + 31516633 = 31516692
61 + 31516631 = 31516692
73 + 31516619 = 31516692
79 + 31516613 = 31516692
89 + 31516603 = 31516692
149 + 31516543 = 31516692
173 + 31516519 = 31516692

Showing the first eight; more decompositions exist.
