Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31509056, here are decompositions:

3 + 31509053 = 31509056
97 + 31508959 = 31509056
109 + 31508947 = 31509056
193 + 31508863 = 31509056
199 + 31508857 = 31509056
373 + 31508683 = 31509056
379 + 31508677 = 31509056
409 + 31508647 = 31509056

Showing the first eight; more decompositions exist.
