Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457464, here are decompositions:

11 + 31457453 = 31457464
53 + 31457411 = 31457464
167 + 31457297 = 31457464
197 + 31457267 = 31457464
263 + 31457201 = 31457464
293 + 31457171 = 31457464
383 + 31457081 = 31457464
677 + 31456787 = 31457464

Showing the first eight; more decompositions exist.
