Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458048, here are decompositions:

59 + 31457989 = 31458048
79 + 31457969 = 31458048
137 + 31457911 = 31458048
179 + 31457869 = 31458048
191 + 31457857 = 31458048
199 + 31457849 = 31458048
227 + 31457821 = 31458048
229 + 31457819 = 31458048

Showing the first eight; more decompositions exist.
