Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514892, here are decompositions:

23 + 31514869 = 31514892
43 + 31514849 = 31514892
53 + 31514839 = 31514892
103 + 31514789 = 31514892
109 + 31514783 = 31514892
151 + 31514741 = 31514892
229 + 31514663 = 31514892
239 + 31514653 = 31514892

Showing the first eight; more decompositions exist.
