Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477912, here are decompositions:

5 + 31477907 = 31477912
29 + 31477883 = 31477912
41 + 31477871 = 31477912
71 + 31477841 = 31477912
101 + 31477811 = 31477912
113 + 31477799 = 31477912
131 + 31477781 = 31477912
359 + 31477553 = 31477912

Showing the first eight; more decompositions exist.
