Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22528, here are decompositions:

17 + 22511 = 22528
47 + 22481 = 22528
59 + 22469 = 22528
131 + 22397 = 22528
137 + 22391 = 22528
179 + 22349 = 22528
251 + 22277 = 22528
257 + 22271 = 22528

Showing the first eight; more decompositions exist.
