Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457026, here are decompositions:

17 + 31457009 = 31457026
89 + 31456937 = 31457026
197 + 31456829 = 31457026
239 + 31456787 = 31457026
257 + 31456769 = 31457026
347 + 31456679 = 31457026
479 + 31456547 = 31457026
509 + 31456517 = 31457026

Showing the first eight; more decompositions exist.
