Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477168, here are decompositions:

5 + 31477163 = 31477168
89 + 31477079 = 31477168
101 + 31477067 = 31477168
251 + 31476917 = 31477168
347 + 31476821 = 31477168
557 + 31476611 = 31477168
617 + 31476551 = 31477168
659 + 31476509 = 31477168

Showing the first eight; more decompositions exist.
