Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477134, here are decompositions:

23 + 31477111 = 31477134
67 + 31477067 = 31477134
71 + 31477063 = 31477134
83 + 31477051 = 31477134
107 + 31477027 = 31477134
113 + 31477021 = 31477134
263 + 31476871 = 31477134
281 + 31476853 = 31477134

Showing the first eight; more decompositions exist.
