Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31509176, here are decompositions:

3 + 31509173 = 31509176
7 + 31509169 = 31509176
19 + 31509157 = 31509176
37 + 31509139 = 31509176
229 + 31508947 = 31509176
313 + 31508863 = 31509176
463 + 31508713 = 31509176
499 + 31508677 = 31509176

Showing the first eight; more decompositions exist.
