Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594656, here are decompositions:

29 + 31594627 = 31594656
43 + 31594613 = 31594656
47 + 31594609 = 31594656
59 + 31594597 = 31594656
73 + 31594583 = 31594656
83 + 31594573 = 31594656
103 + 31594553 = 31594656
109 + 31594547 = 31594656

Showing the first eight; more decompositions exist.
