Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594650, here are decompositions:

23 + 31594627 = 31594650
37 + 31594613 = 31594650
41 + 31594609 = 31594650
53 + 31594597 = 31594650
67 + 31594583 = 31594650
71 + 31594579 = 31594650
97 + 31594553 = 31594650
103 + 31594547 = 31594650

Showing the first eight; more decompositions exist.
