Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594584, here are decompositions:

5 + 31594579 = 31594584
11 + 31594573 = 31594584
31 + 31594553 = 31594584
37 + 31594547 = 31594584
83 + 31594501 = 31594584
163 + 31594421 = 31594584
191 + 31594393 = 31594584
211 + 31594373 = 31594584

Showing the first eight; more decompositions exist.
