Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477108, here are decompositions:

29 + 31477079 = 31477108
41 + 31477067 = 31477108
149 + 31476959 = 31477108
191 + 31476917 = 31477108
227 + 31476881 = 31477108
521 + 31476587 = 31477108
557 + 31476551 = 31477108
599 + 31476509 = 31477108

Showing the first eight; more decompositions exist.
