Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31509414, here are decompositions:

7 + 31509407 = 31509414
11 + 31509403 = 31509414
43 + 31509371 = 31509414
71 + 31509343 = 31509414
107 + 31509307 = 31509414
163 + 31509251 = 31509414
193 + 31509221 = 31509414
197 + 31509217 = 31509414

Showing the first eight; more decompositions exist.
