Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594644, here are decompositions:

17 + 31594627 = 31594644
31 + 31594613 = 31594644
47 + 31594597 = 31594644
61 + 31594583 = 31594644
71 + 31594573 = 31594644
97 + 31594547 = 31594644
181 + 31594463 = 31594644
223 + 31594421 = 31594644

Showing the first eight; more decompositions exist.
