Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514964, here are decompositions:

17 + 31514947 = 31514964
31 + 31514933 = 31514964
53 + 31514911 = 31514964
71 + 31514893 = 31514964
127 + 31514837 = 31514964
181 + 31514783 = 31514964
193 + 31514771 = 31514964
223 + 31514741 = 31514964

Showing the first eight; more decompositions exist.
