Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477764, here are decompositions:

5 + 31477759 = 31477764
11 + 31477753 = 31477764
13 + 31477751 = 31477764
41 + 31477723 = 31477764
47 + 31477717 = 31477764
53 + 31477711 = 31477764
67 + 31477697 = 31477764
107 + 31477657 = 31477764

Showing the first eight; more decompositions exist.
