Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457362, here are decompositions:

59 + 31457303 = 31457362
191 + 31457171 = 31457362
263 + 31457099 = 31457362
269 + 31457093 = 31457362
281 + 31457081 = 31457362
311 + 31457051 = 31457362
353 + 31457009 = 31457362
479 + 31456883 = 31457362

Showing the first eight; more decompositions exist.
