Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594400, here are decompositions:

7 + 31594393 = 31594400
67 + 31594333 = 31594400
127 + 31594273 = 31594400
163 + 31594237 = 31594400
241 + 31594159 = 31594400
337 + 31594063 = 31594400
457 + 31593943 = 31594400
463 + 31593937 = 31594400

Showing the first eight; more decompositions exist.
