Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556716, here are decompositions:

29 + 31556687 = 31556716
179 + 31556537 = 31556716
227 + 31556489 = 31556716
239 + 31556477 = 31556716
293 + 31556423 = 31556716
467 + 31556249 = 31556716
617 + 31556099 = 31556716
683 + 31556033 = 31556716

Showing the first eight; more decompositions exist.
