Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22290, here are decompositions:

7 + 22283 = 22290
11 + 22279 = 22290
13 + 22277 = 22290
17 + 22273 = 22290
19 + 22271 = 22290
31 + 22259 = 22290
43 + 22247 = 22290
61 + 22229 = 22290

Showing the first eight; more decompositions exist.
