Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514916, here are decompositions:

5 + 31514911 = 31514916
23 + 31514893 = 31514916
47 + 31514869 = 31514916
67 + 31514849 = 31514916
79 + 31514837 = 31514916
127 + 31514789 = 31514916
227 + 31514689 = 31514916
229 + 31514687 = 31514916

Showing the first eight; more decompositions exist.
