Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594784, here are decompositions:

37 + 31594747 = 31594784
103 + 31594681 = 31594784
157 + 31594627 = 31594784
211 + 31594573 = 31594784
283 + 31594501 = 31594784
433 + 31594351 = 31594784
547 + 31594237 = 31594784
853 + 31593931 = 31594784

Showing the first eight; more decompositions exist.
