Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457934, here are decompositions:

5 + 31457929 = 31457934
23 + 31457911 = 31457934
31 + 31457903 = 31457934
73 + 31457861 = 31457934
103 + 31457831 = 31457934
113 + 31457821 = 31457934
163 + 31457771 = 31457934
181 + 31457753 = 31457934

Showing the first eight; more decompositions exist.
