Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518796, here are decompositions:

3 + 31518793 = 31518796
17 + 31518779 = 31518796
137 + 31518659 = 31518796
149 + 31518647 = 31518796
443 + 31518353 = 31518796
467 + 31518329 = 31518796
509 + 31518287 = 31518796
557 + 31518239 = 31518796

Showing the first eight; more decompositions exist.
