Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457014, here are decompositions:

5 + 31457009 = 31457014
131 + 31456883 = 31457014
227 + 31456787 = 31457014
233 + 31456781 = 31457014
293 + 31456721 = 31457014
311 + 31456703 = 31457014
467 + 31456547 = 31457014
653 + 31456361 = 31457014

Showing the first eight; more decompositions exist.
