Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594566, here are decompositions:

13 + 31594553 = 31594566
19 + 31594547 = 31594566
103 + 31594463 = 31594566
137 + 31594429 = 31594566
167 + 31594399 = 31594566
173 + 31594393 = 31594566
193 + 31594373 = 31594566
233 + 31594333 = 31594566

Showing the first eight; more decompositions exist.
