Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594724, here are decompositions:

43 + 31594681 = 31594724
97 + 31594627 = 31594724
127 + 31594597 = 31594724
151 + 31594573 = 31594724
223 + 31594501 = 31594724
331 + 31594393 = 31594724
373 + 31594351 = 31594724
487 + 31594237 = 31594724

Showing the first eight; more decompositions exist.
