Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556796, here are decompositions:

17 + 31556779 = 31556796
59 + 31556737 = 31556796
109 + 31556687 = 31556796
149 + 31556647 = 31556796
157 + 31556639 = 31556796
239 + 31556557 = 31556796
307 + 31556489 = 31556796
317 + 31556479 = 31556796

Showing the first eight; more decompositions exist.
