Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566204, here are decompositions:

13 + 31566191 = 31566204
37 + 31566167 = 31566204
53 + 31566151 = 31566204
67 + 31566137 = 31566204
73 + 31566131 = 31566204
127 + 31566077 = 31566204
191 + 31566013 = 31566204
211 + 31565993 = 31566204

Showing the first eight; more decompositions exist.
