Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514052, here are decompositions:

29 + 31514023 = 31514052
109 + 31513943 = 31514052
173 + 31513879 = 31514052
179 + 31513873 = 31514052
233 + 31513819 = 31514052
313 + 31513739 = 31514052
331 + 31513721 = 31514052
359 + 31513693 = 31514052

Showing the first eight; more decompositions exist.
