Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556676, here are decompositions:

23 + 31556653 = 31556676
29 + 31556647 = 31556676
37 + 31556639 = 31556676
139 + 31556537 = 31556676
197 + 31556479 = 31556676
199 + 31556477 = 31556676
269 + 31556407 = 31556676
353 + 31556323 = 31556676

Showing the first eight; more decompositions exist.
