Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471334, here are decompositions:

3 + 31471331 = 31471334
127 + 31471207 = 31471334
163 + 31471171 = 31471334
211 + 31471123 = 31471334
241 + 31471093 = 31471334
283 + 31471051 = 31471334
337 + 31470997 = 31471334
421 + 31470913 = 31471334

Showing the first eight; more decompositions exist.
