Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556706, here are decompositions:

19 + 31556687 = 31556706
53 + 31556653 = 31556706
59 + 31556647 = 31556706
67 + 31556639 = 31556706
149 + 31556557 = 31556706
227 + 31556479 = 31556706
229 + 31556477 = 31556706
239 + 31556467 = 31556706

Showing the first eight; more decompositions exist.
