Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477164, here are decompositions:

23 + 31477141 = 31477164
53 + 31477111 = 31477164
97 + 31477067 = 31477164
101 + 31477063 = 31477164
107 + 31477057 = 31477164
113 + 31477051 = 31477164
137 + 31477027 = 31477164
233 + 31476931 = 31477164

Showing the first eight; more decompositions exist.
