Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457416, here are decompositions:

5 + 31457411 = 31457416
113 + 31457303 = 31457416
149 + 31457267 = 31457416
257 + 31457159 = 31457416
317 + 31457099 = 31457416
467 + 31456949 = 31457416
479 + 31456937 = 31457416
587 + 31456829 = 31457416

Showing the first eight; more decompositions exist.
