Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607646, here are decompositions:

17 + 31607629 = 31607646
47 + 31607599 = 31607646
67 + 31607579 = 31607646
157 + 31607489 = 31607646
173 + 31607473 = 31607646
197 + 31607449 = 31607646
199 + 31607447 = 31607646
223 + 31607423 = 31607646

Showing the first eight; more decompositions exist.
