Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477716, here are decompositions:

5 + 31477711 = 31477716
19 + 31477697 = 31477716
47 + 31477669 = 31477716
59 + 31477657 = 31477716
113 + 31477603 = 31477716
139 + 31477577 = 31477716
163 + 31477553 = 31477716
167 + 31477549 = 31477716

Showing the first eight; more decompositions exist.
