Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477766, here are decompositions:

7 + 31477759 = 31477766
13 + 31477753 = 31477766
37 + 31477729 = 31477766
43 + 31477723 = 31477766
97 + 31477669 = 31477766
109 + 31477657 = 31477766
163 + 31477603 = 31477766
223 + 31477543 = 31477766

Showing the first eight; more decompositions exist.
