Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536234, here are decompositions:

7 + 31536227 = 31536234
11 + 31536223 = 31536234
31 + 31536203 = 31536234
47 + 31536187 = 31536234
73 + 31536161 = 31536234
137 + 31536097 = 31536234
173 + 31536061 = 31536234
181 + 31536053 = 31536234

Showing the first eight; more decompositions exist.
