Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593646, here are decompositions:

3 + 31593643 = 31593646
5 + 31593641 = 31593646
17 + 31593629 = 31593646
83 + 31593563 = 31593646
113 + 31593533 = 31593646
167 + 31593479 = 31593646
257 + 31593389 = 31593646
269 + 31593377 = 31593646

Showing the first eight; more decompositions exist.
