Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31509362, here are decompositions:

13 + 31509349 = 31509362
19 + 31509343 = 31509362
193 + 31509169 = 31509362
223 + 31509139 = 31509362
271 + 31509091 = 31509362
331 + 31509031 = 31509362
499 + 31508863 = 31509362
571 + 31508791 = 31509362

Showing the first eight; more decompositions exist.
