Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594074, here are decompositions:

11 + 31594063 = 31594074
13 + 31594061 = 31594074
131 + 31593943 = 31594074
137 + 31593937 = 31594074
173 + 31593901 = 31594074
241 + 31593833 = 31594074
277 + 31593797 = 31594074
307 + 31593767 = 31594074

Showing the first eight; more decompositions exist.
