Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457094, here are decompositions:

13 + 31457081 = 31457094
23 + 31457071 = 31457094
43 + 31457051 = 31457094
157 + 31456937 = 31457094
167 + 31456927 = 31457094
191 + 31456903 = 31457094
211 + 31456883 = 31457094
307 + 31456787 = 31457094

Showing the first eight; more decompositions exist.
