Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543694, here are decompositions:

3 + 31543691 = 31543694
151 + 31543543 = 31543694
163 + 31543531 = 31543694
241 + 31543453 = 31543694
421 + 31543273 = 31543694
463 + 31543231 = 31543694
487 + 31543207 = 31543694
727 + 31542967 = 31543694

Showing the first eight; more decompositions exist.
