Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514226, here are decompositions:

5 + 31514221 = 31514226
67 + 31514159 = 31514226
83 + 31514143 = 31514226
113 + 31514113 = 31514226
167 + 31514059 = 31514226
239 + 31513987 = 31514226
269 + 31513957 = 31514226
283 + 31513943 = 31514226

Showing the first eight; more decompositions exist.
