Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458084, here are decompositions:

23 + 31458061 = 31458084
71 + 31458013 = 31458084
173 + 31457911 = 31458084
181 + 31457903 = 31458084
223 + 31457861 = 31458084
227 + 31457857 = 31458084
241 + 31457843 = 31458084
263 + 31457821 = 31458084

Showing the first eight; more decompositions exist.
