Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477038, here are decompositions:

11 + 31477027 = 31477038
17 + 31477021 = 31477038
79 + 31476959 = 31477038
107 + 31476931 = 31477038
157 + 31476881 = 31477038
167 + 31476871 = 31477038
191 + 31476847 = 31477038
239 + 31476799 = 31477038

Showing the first eight; more decompositions exist.
