Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25528, here are decompositions:

5 + 25523 = 25528
59 + 25469 = 25528
71 + 25457 = 25528
89 + 25439 = 25528
137 + 25391 = 25528
179 + 25349 = 25528
227 + 25301 = 25528
281 + 25247 = 25528

Showing the first eight; more decompositions exist.
