Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594426, here are decompositions:

5 + 31594421 = 31594426
53 + 31594373 = 31594426
179 + 31594247 = 31594426
233 + 31594193 = 31594426
263 + 31594163 = 31594426
293 + 31594133 = 31594426
443 + 31593983 = 31594426
467 + 31593959 = 31594426

Showing the first eight; more decompositions exist.
