Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502656, here are decompositions:

167 + 31502489 = 31502656
173 + 31502483 = 31502656
197 + 31502459 = 31502656
293 + 31502363 = 31502656
443 + 31502213 = 31502656
467 + 31502189 = 31502656
509 + 31502147 = 31502656
557 + 31502099 = 31502656

Showing the first eight; more decompositions exist.
