Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477080, here are decompositions:

13 + 31477067 = 31477080
17 + 31477063 = 31477080
23 + 31477057 = 31477080
29 + 31477051 = 31477080
53 + 31477027 = 31477080
59 + 31477021 = 31477080
149 + 31476931 = 31477080
163 + 31476917 = 31477080

Showing the first eight; more decompositions exist.
