Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458256, here are decompositions:

17 + 31458239 = 31458256
59 + 31458197 = 31458256
83 + 31458173 = 31458256
173 + 31458083 = 31458256
257 + 31457999 = 31458256
353 + 31457903 = 31458256
503 + 31457753 = 31458256
569 + 31457687 = 31458256

Showing the first eight; more decompositions exist.
