Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458054, here are decompositions:

41 + 31458013 = 31458054
151 + 31457903 = 31458054
193 + 31457861 = 31458054
197 + 31457857 = 31458054
211 + 31457843 = 31458054
223 + 31457831 = 31458054
233 + 31457821 = 31458054
283 + 31457771 = 31458054

Showing the first eight; more decompositions exist.
