Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566096, here are decompositions:

13 + 31566083 = 31566096
17 + 31566079 = 31566096
19 + 31566077 = 31566096
53 + 31566043 = 31566096
83 + 31566013 = 31566096
103 + 31565993 = 31566096
127 + 31565969 = 31566096
167 + 31565929 = 31566096

Showing the first eight; more decompositions exist.
