Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594850, here are decompositions:

37 + 31594813 = 31594850
43 + 31594807 = 31594850
103 + 31594747 = 31594850
151 + 31594699 = 31594850
223 + 31594627 = 31594850
241 + 31594609 = 31594850
271 + 31594579 = 31594850
277 + 31594573 = 31594850

Showing the first eight; more decompositions exist.
