Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536258, here are decompositions:

31 + 31536227 = 31536258
71 + 31536187 = 31536258
97 + 31536161 = 31536258
157 + 31536101 = 31536258
197 + 31536061 = 31536258
239 + 31536019 = 31536258
241 + 31536017 = 31536258
277 + 31535981 = 31536258

Showing the first eight; more decompositions exist.
