Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524646, here are decompositions:

3 + 31524643 = 31524646
5 + 31524641 = 31524646
59 + 31524587 = 31524646
113 + 31524533 = 31524646
137 + 31524509 = 31524646
227 + 31524419 = 31524646
353 + 31524293 = 31524646
389 + 31524257 = 31524646

Showing the first eight; more decompositions exist.
