Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457726, here are decompositions:

7 + 31457719 = 31457726
19 + 31457707 = 31457726
277 + 31457449 = 31457726
379 + 31457347 = 31457726
397 + 31457329 = 31457726
439 + 31457287 = 31457726
457 + 31457269 = 31457726
499 + 31457227 = 31457726

Showing the first eight; more decompositions exist.
