Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536210, here are decompositions:

7 + 31536203 = 31536210
23 + 31536187 = 31536210
109 + 31536101 = 31536210
113 + 31536097 = 31536210
149 + 31536061 = 31536210
157 + 31536053 = 31536210
191 + 31536019 = 31536210
193 + 31536017 = 31536210

Showing the first eight; more decompositions exist.
