Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514256, here are decompositions:

17 + 31514239 = 31514256
97 + 31514159 = 31514256
107 + 31514149 = 31514256
113 + 31514143 = 31514256
197 + 31514059 = 31514256
233 + 31514023 = 31514256
269 + 31513987 = 31514256
313 + 31513943 = 31514256

Showing the first eight; more decompositions exist.
