Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536198, here are decompositions:

11 + 31536187 = 31536198
37 + 31536161 = 31536198
97 + 31536101 = 31536198
101 + 31536097 = 31536198
137 + 31536061 = 31536198
149 + 31536049 = 31536198
179 + 31536019 = 31536198
181 + 31536017 = 31536198

Showing the first eight; more decompositions exist.
