Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514150, here are decompositions:

7 + 31514143 = 31514150
37 + 31514113 = 31514150
127 + 31514023 = 31514150
163 + 31513987 = 31514150
193 + 31513957 = 31514150
223 + 31513927 = 31514150
271 + 31513879 = 31514150
277 + 31513873 = 31514150

Showing the first eight; more decompositions exist.
