Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594790, here are decompositions:

43 + 31594747 = 31594790
61 + 31594729 = 31594790
109 + 31594681 = 31594790
163 + 31594627 = 31594790
181 + 31594609 = 31594790
193 + 31594597 = 31594790
211 + 31594579 = 31594790
397 + 31594393 = 31594790

Showing the first eight; more decompositions exist.
