Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457052, here are decompositions:

13 + 31457039 = 31457052
43 + 31457009 = 31457052
103 + 31456949 = 31457052
149 + 31456903 = 31457052
223 + 31456829 = 31457052
233 + 31456819 = 31457052
271 + 31456781 = 31457052
283 + 31456769 = 31457052

Showing the first eight; more decompositions exist.
