Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514826, here are decompositions:

37 + 31514789 = 31514826
43 + 31514783 = 31514826
137 + 31514689 = 31514826
139 + 31514687 = 31514826
163 + 31514663 = 31514826
173 + 31514653 = 31514826
197 + 31514629 = 31514826
199 + 31514627 = 31514826

Showing the first eight; more decompositions exist.
