Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543352, here are decompositions:

3 + 31543349 = 31543352
79 + 31543273 = 31543352
109 + 31543243 = 31543352
283 + 31543069 = 31543352
409 + 31542943 = 31543352
523 + 31542829 = 31543352
541 + 31542811 = 31543352
739 + 31542613 = 31543352

Showing the first eight; more decompositions exist.
