Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543412, here are decompositions:

139 + 31543273 = 31543412
181 + 31543231 = 31543412
193 + 31543219 = 31543412
421 + 31542991 = 31543412
463 + 31542949 = 31543412
601 + 31542811 = 31543412
613 + 31542799 = 31543412
709 + 31542703 = 31543412

Showing the first eight; more decompositions exist.
