Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566036, here are decompositions:

17 + 31566019 = 31566036
23 + 31566013 = 31566036
43 + 31565993 = 31566036
67 + 31565969 = 31566036
83 + 31565953 = 31566036
107 + 31565929 = 31566036
149 + 31565887 = 31566036
167 + 31565869 = 31566036

Showing the first eight; more decompositions exist.
