Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536290, here are decompositions:

3 + 31536287 = 31536290
67 + 31536223 = 31536290
103 + 31536187 = 31536290
193 + 31536097 = 31536290
229 + 31536061 = 31536290
241 + 31536049 = 31536290
271 + 31536019 = 31536290
307 + 31535983 = 31536290

Showing the first eight; more decompositions exist.
