Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594568, here are decompositions:

67 + 31594501 = 31594568
79 + 31594489 = 31594568
139 + 31594429 = 31594568
331 + 31594237 = 31594568
409 + 31594159 = 31594568
487 + 31594081 = 31594568
631 + 31593937 = 31594568
937 + 31593631 = 31594568

Showing the first eight; more decompositions exist.
