Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466724, here are decompositions:

5 + 31466719 = 31466724
11 + 31466713 = 31466724
17 + 31466707 = 31466724
31 + 31466693 = 31466724
53 + 31466671 = 31466724
67 + 31466657 = 31466724
97 + 31466627 = 31466724
127 + 31466597 = 31466724

Showing the first eight; more decompositions exist.
