Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514850, here are decompositions:

11 + 31514839 = 31514850
13 + 31514837 = 31514850
61 + 31514789 = 31514850
67 + 31514783 = 31514850
79 + 31514771 = 31514850
109 + 31514741 = 31514850
163 + 31514687 = 31514850
179 + 31514671 = 31514850

Showing the first eight; more decompositions exist.
