Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22690, here are decompositions:

11 + 22679 = 22690
47 + 22643 = 22690
53 + 22637 = 22690
71 + 22619 = 22690
149 + 22541 = 22690
179 + 22511 = 22690
257 + 22433 = 22690
281 + 22409 = 22690

Showing the first eight; more decompositions exist.
