Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536398, here are decompositions:

7 + 31536391 = 31536398
37 + 31536361 = 31536398
211 + 31536187 = 31536398
337 + 31536061 = 31536398
349 + 31536049 = 31536398
379 + 31536019 = 31536398
457 + 31535941 = 31536398
571 + 31535827 = 31536398

Showing the first eight; more decompositions exist.
