Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457092, here are decompositions:

11 + 31457081 = 31457092
41 + 31457051 = 31457092
53 + 31457039 = 31457092
83 + 31457009 = 31457092
263 + 31456829 = 31457092
311 + 31456781 = 31457092
353 + 31456739 = 31457092
389 + 31456703 = 31457092

Showing the first eight; more decompositions exist.
