Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514022, here are decompositions:

79 + 31513943 = 31514022
131 + 31513891 = 31514022
149 + 31513873 = 31514022
173 + 31513849 = 31514022
179 + 31513843 = 31514022
191 + 31513831 = 31514022
229 + 31513793 = 31514022
283 + 31513739 = 31514022

Showing the first eight; more decompositions exist.
