Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22666, here are decompositions:

23 + 22643 = 22666
29 + 22637 = 22666
47 + 22619 = 22666
53 + 22613 = 22666
197 + 22469 = 22666
233 + 22433 = 22666
257 + 22409 = 22666
269 + 22397 = 22666

Showing the first eight; more decompositions exist.
