Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457706, here are decompositions:

19 + 31457687 = 31457706
79 + 31457627 = 31457706
103 + 31457603 = 31457706
149 + 31457557 = 31457706
193 + 31457513 = 31457706
227 + 31457479 = 31457706
257 + 31457449 = 31457706
359 + 31457347 = 31457706

Showing the first eight; more decompositions exist.
