Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477146, here are decompositions:

5 + 31477141 = 31477146
47 + 31477099 = 31477146
67 + 31477079 = 31477146
79 + 31477067 = 31477146
83 + 31477063 = 31477146
89 + 31477057 = 31477146
199 + 31476947 = 31477146
229 + 31476917 = 31477146

Showing the first eight; more decompositions exist.
