Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543348, here are decompositions:

17 + 31543331 = 31543348
47 + 31543301 = 31543348
131 + 31543217 = 31543348
167 + 31543181 = 31543348
269 + 31543079 = 31543348
281 + 31543067 = 31543348
467 + 31542881 = 31543348
491 + 31542857 = 31543348

Showing the first eight; more decompositions exist.
