Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457226, here are decompositions:

23 + 31457203 = 31457226
67 + 31457159 = 31457226
107 + 31457119 = 31457226
127 + 31457099 = 31457226
277 + 31456949 = 31457226
397 + 31456829 = 31457226
439 + 31456787 = 31457226
457 + 31456769 = 31457226

Showing the first eight; more decompositions exist.
