Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477950, here are decompositions:

13 + 31477937 = 31477950
43 + 31477907 = 31477950
67 + 31477883 = 31477950
71 + 31477879 = 31477950
73 + 31477877 = 31477950
79 + 31477871 = 31477950
109 + 31477841 = 31477950
139 + 31477811 = 31477950

Showing the first eight; more decompositions exist.
