Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536250, here are decompositions:

23 + 31536227 = 31536250
47 + 31536203 = 31536250
89 + 31536161 = 31536250
149 + 31536101 = 31536250
197 + 31536053 = 31536250
233 + 31536017 = 31536250
269 + 31535981 = 31536250
311 + 31535939 = 31536250

Showing the first eight; more decompositions exist.
