Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566622, here are decompositions:

11 + 31566611 = 31566622
23 + 31566599 = 31566622
149 + 31566473 = 31566622
173 + 31566449 = 31566622
179 + 31566443 = 31566622
233 + 31566389 = 31566622
239 + 31566383 = 31566622
293 + 31566329 = 31566622

Showing the first eight; more decompositions exist.
