Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457096, here are decompositions:

3 + 31457093 = 31457096
193 + 31456903 = 31457096
277 + 31456819 = 31457096
457 + 31456639 = 31457096
499 + 31456597 = 31457096
859 + 31456237 = 31457096
877 + 31456219 = 31457096
997 + 31456099 = 31457096

Showing the first eight; more decompositions exist.
