Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514862, here are decompositions:

13 + 31514849 = 31514862
23 + 31514839 = 31514862
73 + 31514789 = 31514862
79 + 31514783 = 31514862
131 + 31514731 = 31514862
173 + 31514689 = 31514862
191 + 31514671 = 31514862
199 + 31514663 = 31514862

Showing the first eight; more decompositions exist.
