Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457694, here are decompositions:

7 + 31457687 = 31457694
13 + 31457681 = 31457694
53 + 31457641 = 31457694
67 + 31457627 = 31457694
83 + 31457611 = 31457694
137 + 31457557 = 31457694
181 + 31457513 = 31457694
223 + 31457471 = 31457694

Showing the first eight; more decompositions exist.
