Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31509422, here are decompositions:

3 + 31509419 = 31509422
19 + 31509403 = 31509422
73 + 31509349 = 31509422
79 + 31509343 = 31509422
151 + 31509271 = 31509422
283 + 31509139 = 31509422
331 + 31509091 = 31509422
463 + 31508959 = 31509422

Showing the first eight; more decompositions exist.
