Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514986, here are decompositions:

5 + 31514981 = 31514986
17 + 31514969 = 31514986
23 + 31514963 = 31514986
53 + 31514933 = 31514986
137 + 31514849 = 31514986
149 + 31514837 = 31514986
197 + 31514789 = 31514986
359 + 31514627 = 31514986

Showing the first eight; more decompositions exist.
