Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543334, here are decompositions:

3 + 31543331 = 31543334
61 + 31543273 = 31543334
103 + 31543231 = 31543334
127 + 31543207 = 31543334
367 + 31542967 = 31543334
397 + 31542937 = 31543334
457 + 31542877 = 31543334
523 + 31542811 = 31543334

Showing the first eight; more decompositions exist.
