Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31509336, here are decompositions:

7 + 31509329 = 31509336
13 + 31509323 = 31509336
29 + 31509307 = 31509336
163 + 31509173 = 31509336
167 + 31509169 = 31509336
179 + 31509157 = 31509336
197 + 31509139 = 31509336
283 + 31509053 = 31509336

Showing the first eight; more decompositions exist.
