Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514042, here are decompositions:

19 + 31514023 = 31514042
151 + 31513891 = 31514042
163 + 31513879 = 31514042
193 + 31513849 = 31514042
199 + 31513843 = 31514042
211 + 31513831 = 31514042
223 + 31513819 = 31514042
349 + 31513693 = 31514042

Showing the first eight; more decompositions exist.
