Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594716, here are decompositions:

17 + 31594699 = 31594716
89 + 31594627 = 31594716
103 + 31594613 = 31594716
107 + 31594609 = 31594716
137 + 31594579 = 31594716
163 + 31594553 = 31594716
227 + 31594489 = 31594716
317 + 31594399 = 31594716

Showing the first eight; more decompositions exist.
