Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514382, here are decompositions:

73 + 31514309 = 31514382
191 + 31514191 = 31514382
223 + 31514159 = 31514382
233 + 31514149 = 31514382
239 + 31514143 = 31514382
269 + 31514113 = 31514382
281 + 31514101 = 31514382
359 + 31514023 = 31514382

Showing the first eight; more decompositions exist.
