Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594304, here are decompositions:

31 + 31594273 = 31594304
67 + 31594237 = 31594304
223 + 31594081 = 31594304
241 + 31594063 = 31594304
367 + 31593937 = 31594304
373 + 31593931 = 31594304
541 + 31593763 = 31594304
601 + 31593703 = 31594304

Showing the first eight; more decompositions exist.
