Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594808, here are decompositions:

61 + 31594747 = 31594808
79 + 31594729 = 31594808
109 + 31594699 = 31594808
127 + 31594681 = 31594808
181 + 31594627 = 31594808
199 + 31594609 = 31594808
211 + 31594597 = 31594808
229 + 31594579 = 31594808

Showing the first eight; more decompositions exist.
