Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477074, here are decompositions:

7 + 31477067 = 31477074
11 + 31477063 = 31477074
17 + 31477057 = 31477074
23 + 31477051 = 31477074
47 + 31477027 = 31477074
53 + 31477021 = 31477074
127 + 31476947 = 31477074
157 + 31476917 = 31477074

Showing the first eight; more decompositions exist.
