Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458010, here are decompositions:

11 + 31457999 = 31458010
41 + 31457969 = 31458010
107 + 31457903 = 31458010
149 + 31457861 = 31458010
167 + 31457843 = 31458010
179 + 31457831 = 31458010
191 + 31457819 = 31458010
239 + 31457771 = 31458010

Showing the first eight; more decompositions exist.
