Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458112, here are decompositions:

29 + 31458083 = 31458112
113 + 31457999 = 31458112
251 + 31457861 = 31458112
263 + 31457849 = 31458112
269 + 31457843 = 31458112
281 + 31457831 = 31458112
293 + 31457819 = 31458112
353 + 31457759 = 31458112

Showing the first eight; more decompositions exist.
