Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514072, here are decompositions:

13 + 31514059 = 31514072
181 + 31513891 = 31514072
193 + 31513879 = 31514072
199 + 31513873 = 31514072
223 + 31513849 = 31514072
229 + 31513843 = 31514072
241 + 31513831 = 31514072
379 + 31513693 = 31514072

Showing the first eight; more decompositions exist.
