Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594694, here are decompositions:

3 + 31594691 = 31594694
13 + 31594681 = 31594694
67 + 31594627 = 31594694
97 + 31594597 = 31594694
193 + 31594501 = 31594694
421 + 31594273 = 31594694
457 + 31594237 = 31594694
613 + 31594081 = 31594694

Showing the first eight; more decompositions exist.
