Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594222, here are decompositions:

29 + 31594193 = 31594222
59 + 31594163 = 31594222
71 + 31594151 = 31594222
89 + 31594133 = 31594222
173 + 31594049 = 31594222
239 + 31593983 = 31594222
263 + 31593959 = 31594222
269 + 31593953 = 31594222

Showing the first eight; more decompositions exist.
