Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458022, here are decompositions:

23 + 31457999 = 31458022
53 + 31457969 = 31458022
173 + 31457849 = 31458022
179 + 31457843 = 31458022
191 + 31457831 = 31458022
251 + 31457771 = 31458022
263 + 31457759 = 31458022
269 + 31457753 = 31458022

Showing the first eight; more decompositions exist.
