Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31646, here are decompositions:

3 + 31643 = 31646
19 + 31627 = 31646
73 + 31573 = 31646
79 + 31567 = 31646
103 + 31543 = 31646
157 + 31489 = 31646
313 + 31333 = 31646
379 + 31267 = 31646

Showing the first eight; more decompositions exist.
