Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514136, here are decompositions:

23 + 31514113 = 31514136
113 + 31514023 = 31514136
149 + 31513987 = 31514136
179 + 31513957 = 31514136
193 + 31513943 = 31514136
257 + 31513879 = 31514136
263 + 31513873 = 31514136
293 + 31513843 = 31514136

Showing the first eight; more decompositions exist.
