Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514886, here are decompositions:

17 + 31514869 = 31514886
37 + 31514849 = 31514886
47 + 31514839 = 31514886
97 + 31514789 = 31514886
103 + 31514783 = 31514886
197 + 31514689 = 31514886
199 + 31514687 = 31514886
223 + 31514663 = 31514886

Showing the first eight; more decompositions exist.
