Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536246, here are decompositions:

19 + 31536227 = 31536246
23 + 31536223 = 31536246
43 + 31536203 = 31536246
59 + 31536187 = 31536246
149 + 31536097 = 31536246
193 + 31536053 = 31536246
197 + 31536049 = 31536246
227 + 31536019 = 31536246

Showing the first eight; more decompositions exist.
