Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458952, here are decompositions:

29 + 31458923 = 31458952
89 + 31458863 = 31458952
131 + 31458821 = 31458952
191 + 31458761 = 31458952
233 + 31458719 = 31458952
251 + 31458701 = 31458952
263 + 31458689 = 31458952
359 + 31458593 = 31458952

Showing the first eight; more decompositions exist.
