Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536458, here are decompositions:

61 + 31536397 = 31536458
67 + 31536391 = 31536458
97 + 31536361 = 31536458
271 + 31536187 = 31536458
397 + 31536061 = 31536458
409 + 31536049 = 31536458
439 + 31536019 = 31536458
631 + 31535827 = 31536458

Showing the first eight; more decompositions exist.
