Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458852, here are decompositions:

23 + 31458829 = 31458852
31 + 31458821 = 31458852
53 + 31458799 = 31458852
149 + 31458703 = 31458852
151 + 31458701 = 31458852
163 + 31458689 = 31458852
251 + 31458601 = 31458852
263 + 31458589 = 31458852

Showing the first eight; more decompositions exist.
