Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594182, here are decompositions:

19 + 31594163 = 31594182
23 + 31594159 = 31594182
31 + 31594151 = 31594182
101 + 31594081 = 31594182
199 + 31593983 = 31594182
223 + 31593959 = 31594182
229 + 31593953 = 31594182
239 + 31593943 = 31594182

Showing the first eight; more decompositions exist.
