Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594782, here are decompositions:

13 + 31594769 = 31594782
53 + 31594729 = 31594782
83 + 31594699 = 31594782
101 + 31594681 = 31594782
173 + 31594609 = 31594782
199 + 31594583 = 31594782
229 + 31594553 = 31594782
281 + 31594501 = 31594782

Showing the first eight; more decompositions exist.
