Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466676, here are decompositions:

5 + 31466671 = 31466676
19 + 31466657 = 31466676
47 + 31466629 = 31466676
79 + 31466597 = 31466676
89 + 31466587 = 31466676
113 + 31466563 = 31466676
127 + 31466549 = 31466676
173 + 31466503 = 31466676

Showing the first eight; more decompositions exist.
