Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594216, here are decompositions:

23 + 31594193 = 31594216
53 + 31594163 = 31594216
83 + 31594133 = 31594216
167 + 31594049 = 31594216
233 + 31593983 = 31594216
257 + 31593959 = 31594216
263 + 31593953 = 31594216
347 + 31593869 = 31594216

Showing the first eight; more decompositions exist.
