Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457962, here are decompositions:

59 + 31457903 = 31457962
101 + 31457861 = 31457962
113 + 31457849 = 31457962
131 + 31457831 = 31457962
191 + 31457771 = 31457962
233 + 31457729 = 31457962
281 + 31457681 = 31457962
359 + 31457603 = 31457962

Showing the first eight; more decompositions exist.
