Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536438, here are decompositions:

41 + 31536397 = 31536438
47 + 31536391 = 31536438
79 + 31536359 = 31536438
151 + 31536287 = 31536438
211 + 31536227 = 31536438
251 + 31536187 = 31536438
277 + 31536161 = 31536438
337 + 31536101 = 31536438

Showing the first eight; more decompositions exist.
