Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566936, here are decompositions:

17 + 31566919 = 31566936
73 + 31566863 = 31566936
97 + 31566839 = 31566936
109 + 31566827 = 31566936
139 + 31566797 = 31566936
173 + 31566763 = 31566936
199 + 31566737 = 31566936
223 + 31566713 = 31566936

Showing the first eight; more decompositions exist.
