Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514342, here are decompositions:

103 + 31514239 = 31514342
151 + 31514191 = 31514342
193 + 31514149 = 31514342
199 + 31514143 = 31514342
229 + 31514113 = 31514342
241 + 31514101 = 31514342
283 + 31514059 = 31514342
463 + 31513879 = 31514342

Showing the first eight; more decompositions exist.
