Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457476, here are decompositions:

5 + 31457471 = 31457476
23 + 31457453 = 31457476
173 + 31457303 = 31457476
179 + 31457297 = 31457476
317 + 31457159 = 31457476
383 + 31457093 = 31457476
467 + 31457009 = 31457476
593 + 31456883 = 31457476

Showing the first eight; more decompositions exist.
