Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457674, here are decompositions:

47 + 31457627 = 31457674
71 + 31457603 = 31457674
263 + 31457411 = 31457674
503 + 31457171 = 31457674
593 + 31457081 = 31457674
887 + 31456787 = 31457674
947 + 31456727 = 31457674
953 + 31456721 = 31457674

Showing the first eight; more decompositions exist.
