Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594574, here are decompositions:

73 + 31594501 = 31594574
181 + 31594393 = 31594574
223 + 31594351 = 31594574
241 + 31594333 = 31594574
337 + 31594237 = 31594574
631 + 31593943 = 31594574
643 + 31593931 = 31594574
673 + 31593901 = 31594574

Showing the first eight; more decompositions exist.
