Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514982, here are decompositions:

13 + 31514969 = 31514982
19 + 31514963 = 31514982
71 + 31514911 = 31514982
89 + 31514893 = 31514982
113 + 31514869 = 31514982
193 + 31514789 = 31514982
199 + 31514783 = 31514982
211 + 31514771 = 31514982

Showing the first eight; more decompositions exist.
