Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458068, here are decompositions:

7 + 31458061 = 31458068
79 + 31457989 = 31458068
139 + 31457929 = 31458068
157 + 31457911 = 31458068
199 + 31457869 = 31458068
211 + 31457857 = 31458068
331 + 31457737 = 31458068
349 + 31457719 = 31458068

Showing the first eight; more decompositions exist.
