Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514904, here are decompositions:

11 + 31514893 = 31514904
67 + 31514837 = 31514904
163 + 31514741 = 31514904
173 + 31514731 = 31514904
233 + 31514671 = 31514904
241 + 31514663 = 31514904
251 + 31514653 = 31514904
263 + 31514641 = 31514904

Showing the first eight; more decompositions exist.
