Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458246, here are decompositions:

7 + 31458239 = 31458246
59 + 31458187 = 31458246
73 + 31458173 = 31458246
163 + 31458083 = 31458246
233 + 31458013 = 31458246
257 + 31457989 = 31458246
277 + 31457969 = 31458246
317 + 31457929 = 31458246

Showing the first eight; more decompositions exist.
