Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536216, here are decompositions:

13 + 31536203 = 31536216
29 + 31536187 = 31536216
163 + 31536053 = 31536216
167 + 31536049 = 31536216
197 + 31536019 = 31536216
199 + 31536017 = 31536216
233 + 31535983 = 31536216
269 + 31535947 = 31536216

Showing the first eight; more decompositions exist.
