Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594306, here are decompositions:

59 + 31594247 = 31594306
113 + 31594193 = 31594306
173 + 31594133 = 31594306
257 + 31594049 = 31594306
347 + 31593959 = 31594306
353 + 31593953 = 31594306
467 + 31593839 = 31594306
509 + 31593797 = 31594306

Showing the first eight; more decompositions exist.
