Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514854, here are decompositions:

5 + 31514849 = 31514854
17 + 31514837 = 31514854
71 + 31514783 = 31514854
83 + 31514771 = 31514854
113 + 31514741 = 31514854
167 + 31514687 = 31514854
191 + 31514663 = 31514854
227 + 31514627 = 31514854

Showing the first eight; more decompositions exist.
