Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514938, here are decompositions:

5 + 31514933 = 31514938
89 + 31514849 = 31514938
101 + 31514837 = 31514938
149 + 31514789 = 31514938
167 + 31514771 = 31514938
197 + 31514741 = 31514938
251 + 31514687 = 31514938
311 + 31514627 = 31514938

Showing the first eight; more decompositions exist.
