Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457704, here are decompositions:

17 + 31457687 = 31457704
23 + 31457681 = 31457704
101 + 31457603 = 31457704
191 + 31457513 = 31457704
233 + 31457471 = 31457704
251 + 31457453 = 31457704
293 + 31457411 = 31457704
401 + 31457303 = 31457704

Showing the first eight; more decompositions exist.
