Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594824, here are decompositions:

11 + 31594813 = 31594824
13 + 31594811 = 31594824
17 + 31594807 = 31594824
67 + 31594757 = 31594824
97 + 31594727 = 31594824
197 + 31594627 = 31594824
211 + 31594613 = 31594824
227 + 31594597 = 31594824

Showing the first eight; more decompositions exist.
