Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457016, here are decompositions:

7 + 31457009 = 31457016
67 + 31456949 = 31457016
79 + 31456937 = 31457016
89 + 31456927 = 31457016
113 + 31456903 = 31457016
167 + 31456849 = 31457016
197 + 31456819 = 31457016
229 + 31456787 = 31457016

Showing the first eight; more decompositions exist.
