Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477966, here are decompositions:

29 + 31477937 = 31477966
59 + 31477907 = 31477966
83 + 31477883 = 31477966
89 + 31477877 = 31477966
167 + 31477799 = 31477966
173 + 31477793 = 31477966
269 + 31477697 = 31477966
383 + 31477583 = 31477966

Showing the first eight; more decompositions exist.
