Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594390, here are decompositions:

17 + 31594373 = 31594390
59 + 31594331 = 31594390
197 + 31594193 = 31594390
227 + 31594163 = 31594390
239 + 31594151 = 31594390
257 + 31594133 = 31594390
293 + 31594097 = 31594390
431 + 31593959 = 31594390

Showing the first eight; more decompositions exist.
