Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514970, here are decompositions:

7 + 31514963 = 31514970
23 + 31514947 = 31514970
37 + 31514933 = 31514970
59 + 31514911 = 31514970
101 + 31514869 = 31514970
131 + 31514839 = 31514970
181 + 31514789 = 31514970
199 + 31514771 = 31514970

Showing the first eight; more decompositions exist.
