Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566196, here are decompositions:

5 + 31566191 = 31566196
29 + 31566167 = 31566196
59 + 31566137 = 31566196
113 + 31566083 = 31566196
227 + 31565969 = 31566196
503 + 31565693 = 31566196
593 + 31565603 = 31566196
773 + 31565423 = 31566196

Showing the first eight; more decompositions exist.
