Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543502, here are decompositions:

13 + 31543489 = 31543502
73 + 31543429 = 31543502
229 + 31543273 = 31543502
271 + 31543231 = 31543502
283 + 31543219 = 31543502
433 + 31543069 = 31543502
673 + 31542829 = 31543502
691 + 31542811 = 31543502

Showing the first eight; more decompositions exist.
