Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477944, here are decompositions:

7 + 31477937 = 31477944
37 + 31477907 = 31477944
61 + 31477883 = 31477944
67 + 31477877 = 31477944
73 + 31477871 = 31477944
103 + 31477841 = 31477944
151 + 31477793 = 31477944
163 + 31477781 = 31477944

Showing the first eight; more decompositions exist.
