Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477776, here are decompositions:

17 + 31477759 = 31477776
23 + 31477753 = 31477776
47 + 31477729 = 31477776
53 + 31477723 = 31477776
59 + 31477717 = 31477776
79 + 31477697 = 31477776
107 + 31477669 = 31477776
173 + 31477603 = 31477776

Showing the first eight; more decompositions exist.
