Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516696, here are decompositions:

83 + 31516613 = 31516696
137 + 31516559 = 31516696
173 + 31516523 = 31516696
227 + 31516469 = 31516696
269 + 31516427 = 31516696
317 + 31516379 = 31516696
443 + 31516253 = 31516696
557 + 31516139 = 31516696

Showing the first eight; more decompositions exist.
