Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514936, here are decompositions:

3 + 31514933 = 31514936
43 + 31514893 = 31514936
67 + 31514869 = 31514936
97 + 31514839 = 31514936
283 + 31514653 = 31514936
307 + 31514629 = 31514936
337 + 31514599 = 31514936
457 + 31514479 = 31514936

Showing the first eight; more decompositions exist.
