Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567646, here are decompositions:

3 + 31567643 = 31567646
43 + 31567603 = 31567646
277 + 31567369 = 31567646
349 + 31567297 = 31567646
367 + 31567279 = 31567646
379 + 31567267 = 31567646
433 + 31567213 = 31567646
673 + 31566973 = 31567646

Showing the first eight; more decompositions exist.
