Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457404, here are decompositions:

101 + 31457303 = 31457404
107 + 31457297 = 31457404
137 + 31457267 = 31457404
233 + 31457171 = 31457404
311 + 31457093 = 31457404
353 + 31457051 = 31457404
467 + 31456937 = 31457404
521 + 31456883 = 31457404

Showing the first eight; more decompositions exist.
