Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556922, here are decompositions:

11 + 31556911 = 31556922
13 + 31556909 = 31556922
53 + 31556869 = 31556922
109 + 31556813 = 31556922
151 + 31556771 = 31556922
181 + 31556741 = 31556922
269 + 31556653 = 31556922
283 + 31556639 = 31556922

Showing the first eight; more decompositions exist.
