Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457896, here are decompositions:

47 + 31457849 = 31457896
53 + 31457843 = 31457896
137 + 31457759 = 31457896
167 + 31457729 = 31457896
179 + 31457717 = 31457896
269 + 31457627 = 31457896
293 + 31457603 = 31457896
383 + 31457513 = 31457896

Showing the first eight; more decompositions exist.
