Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566922, here are decompositions:

3 + 31566919 = 31566922
11 + 31566911 = 31566922
59 + 31566863 = 31566922
83 + 31566839 = 31566922
173 + 31566749 = 31566922
263 + 31566659 = 31566922
311 + 31566611 = 31566922
449 + 31566473 = 31566922

Showing the first eight; more decompositions exist.
