Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530676, here are decompositions:

17 + 31530659 = 31530676
59 + 31530617 = 31530676
83 + 31530593 = 31530676
179 + 31530497 = 31530676
197 + 31530479 = 31530676
239 + 31530437 = 31530676
257 + 31530419 = 31530676
293 + 31530383 = 31530676

Showing the first eight; more decompositions exist.
