Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477914, here are decompositions:

7 + 31477907 = 31477914
31 + 31477883 = 31477914
37 + 31477877 = 31477914
43 + 31477871 = 31477914
73 + 31477841 = 31477914
103 + 31477811 = 31477914
163 + 31477751 = 31477914
191 + 31477723 = 31477914

Showing the first eight; more decompositions exist.
