Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514794, here are decompositions:

5 + 31514789 = 31514794
11 + 31514783 = 31514794
23 + 31514771 = 31514794
53 + 31514741 = 31514794
107 + 31514687 = 31514794
131 + 31514663 = 31514794
167 + 31514627 = 31514794
257 + 31514537 = 31514794

Showing the first eight; more decompositions exist.
