Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594164, here are decompositions:

5 + 31594159 = 31594164
13 + 31594151 = 31594164
31 + 31594133 = 31594164
67 + 31594097 = 31594164
83 + 31594081 = 31594164
101 + 31594063 = 31594164
103 + 31594061 = 31594164
181 + 31593983 = 31594164

Showing the first eight; more decompositions exist.
