Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543466, here are decompositions:

13 + 31543453 = 31543466
37 + 31543429 = 31543466
193 + 31543273 = 31543466
223 + 31543243 = 31543466
397 + 31543069 = 31543466
457 + 31543009 = 31543466
499 + 31542967 = 31543466
523 + 31542943 = 31543466

Showing the first eight; more decompositions exist.
