Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477116, here are decompositions:

5 + 31477111 = 31477116
17 + 31477099 = 31477116
37 + 31477079 = 31477116
53 + 31477063 = 31477116
59 + 31477057 = 31477116
89 + 31477027 = 31477116
157 + 31476959 = 31477116
199 + 31476917 = 31477116

Showing the first eight; more decompositions exist.
