Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458088, here are decompositions:

5 + 31458083 = 31458088
89 + 31457999 = 31458088
227 + 31457861 = 31458088
239 + 31457849 = 31458088
257 + 31457831 = 31458088
269 + 31457819 = 31458088
317 + 31457771 = 31458088
359 + 31457729 = 31458088

Showing the first eight; more decompositions exist.
