Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516826, here are decompositions:

7 + 31516819 = 31516826
37 + 31516789 = 31516826
73 + 31516753 = 31516826
97 + 31516729 = 31516826
127 + 31516699 = 31516826
157 + 31516669 = 31516826
193 + 31516633 = 31516826
199 + 31516627 = 31516826

Showing the first eight; more decompositions exist.
