Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466694, here are decompositions:

5 + 31466689 = 31466694
23 + 31466671 = 31466694
37 + 31466657 = 31466694
67 + 31466627 = 31466694
97 + 31466597 = 31466694
107 + 31466587 = 31466694
131 + 31466563 = 31466694
191 + 31466503 = 31466694

Showing the first eight; more decompositions exist.
