Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594686, here are decompositions:

5 + 31594681 = 31594686
59 + 31594627 = 31594686
73 + 31594613 = 31594686
89 + 31594597 = 31594686
103 + 31594583 = 31594686
107 + 31594579 = 31594686
113 + 31594573 = 31594686
139 + 31594547 = 31594686

Showing the first eight; more decompositions exist.
