Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477150, here are decompositions:

71 + 31477079 = 31477150
83 + 31477067 = 31477150
191 + 31476959 = 31477150
233 + 31476917 = 31477150
269 + 31476881 = 31477150
557 + 31476593 = 31477150
563 + 31476587 = 31477150
599 + 31476551 = 31477150

Showing the first eight; more decompositions exist.
