Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539632, here are decompositions:

109 + 31539523 = 31539632
193 + 31539439 = 31539632
211 + 31539421 = 31539632
283 + 31539349 = 31539632
349 + 31539283 = 31539632
571 + 31539061 = 31539632
853 + 31538779 = 31539632
919 + 31538713 = 31539632

Showing the first eight; more decompositions exist.
