Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477092, here are decompositions:

13 + 31477079 = 31477092
29 + 31477063 = 31477092
41 + 31477051 = 31477092
71 + 31477021 = 31477092
211 + 31476881 = 31477092
239 + 31476853 = 31477092
263 + 31476829 = 31477092
271 + 31476821 = 31477092

Showing the first eight; more decompositions exist.
