Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536644, here are decompositions:

31 + 31536613 = 31536644
37 + 31536607 = 31536644
163 + 31536481 = 31536644
241 + 31536403 = 31536644
283 + 31536361 = 31536644
331 + 31536313 = 31536644
421 + 31536223 = 31536644
457 + 31536187 = 31536644

Showing the first eight; more decompositions exist.
