Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457032, here are decompositions:

23 + 31457009 = 31457032
83 + 31456949 = 31457032
149 + 31456883 = 31457032
251 + 31456781 = 31457032
263 + 31456769 = 31457032
293 + 31456739 = 31457032
311 + 31456721 = 31457032
353 + 31456679 = 31457032

Showing the first eight; more decompositions exist.
