Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458006, here are decompositions:

7 + 31457999 = 31458006
17 + 31457989 = 31458006
37 + 31457969 = 31458006
103 + 31457903 = 31458006
137 + 31457869 = 31458006
149 + 31457857 = 31458006
157 + 31457849 = 31458006
163 + 31457843 = 31458006

Showing the first eight; more decompositions exist.
