Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534756, here are decompositions:

3 + 31534753 = 31534756
5 + 31534751 = 31534756
17 + 31534739 = 31534756
47 + 31534709 = 31534756
167 + 31534589 = 31534756
263 + 31534493 = 31534756
269 + 31534487 = 31534756
509 + 31534247 = 31534756

Showing the first eight; more decompositions exist.
