Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594266, here are decompositions:

19 + 31594247 = 31594266
29 + 31594237 = 31594266
73 + 31594193 = 31594266
103 + 31594163 = 31594266
107 + 31594159 = 31594266
227 + 31594039 = 31594266
283 + 31593983 = 31594266
307 + 31593959 = 31594266

Showing the first eight; more decompositions exist.
