Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543514, here are decompositions:

61 + 31543453 = 31543514
241 + 31543273 = 31543514
271 + 31543243 = 31543514
283 + 31543231 = 31543514
307 + 31543207 = 31543514
523 + 31542991 = 31543514
547 + 31542967 = 31543514
571 + 31542943 = 31543514

Showing the first eight; more decompositions exist.
