Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594958, here are decompositions:

97 + 31594861 = 31594958
151 + 31594807 = 31594958
211 + 31594747 = 31594958
229 + 31594729 = 31594958
277 + 31594681 = 31594958
331 + 31594627 = 31594958
349 + 31594609 = 31594958
379 + 31594579 = 31594958

Showing the first eight; more decompositions exist.
