Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477676, here are decompositions:

7 + 31477669 = 31477676
19 + 31477657 = 31477676
73 + 31477603 = 31477676
127 + 31477549 = 31477676
163 + 31477513 = 31477676
193 + 31477483 = 31477676
229 + 31477447 = 31477676
277 + 31477399 = 31477676

Showing the first eight; more decompositions exist.
