Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566722, here are decompositions:

13 + 31566709 = 31566722
163 + 31566559 = 31566722
181 + 31566541 = 31566722
199 + 31566523 = 31566722
241 + 31566481 = 31566722
373 + 31566349 = 31566722
433 + 31566289 = 31566722
571 + 31566151 = 31566722

Showing the first eight; more decompositions exist.
