Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458994, here are decompositions:

11 + 31458983 = 31458994
41 + 31458953 = 31458994
71 + 31458923 = 31458994
131 + 31458863 = 31458994
173 + 31458821 = 31458994
197 + 31458797 = 31458994
233 + 31458761 = 31458994
293 + 31458701 = 31458994

Showing the first eight; more decompositions exist.
