Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594292, here are decompositions:

19 + 31594273 = 31594292
211 + 31594081 = 31594292
229 + 31594063 = 31594292
349 + 31593943 = 31594292
571 + 31593721 = 31594292
661 + 31593631 = 31594292
739 + 31593553 = 31594292
1039 + 31593253 = 31594292

Showing the first eight; more decompositions exist.
