Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594692, here are decompositions:

11 + 31594681 = 31594692
79 + 31594613 = 31594692
83 + 31594609 = 31594692
109 + 31594583 = 31594692
113 + 31594579 = 31594692
139 + 31594553 = 31594692
191 + 31594501 = 31594692
229 + 31594463 = 31594692

Showing the first eight; more decompositions exist.
