Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28534, here are decompositions:

17 + 28517 = 28534
41 + 28493 = 28534
71 + 28463 = 28534
101 + 28433 = 28534
131 + 28403 = 28534
227 + 28307 = 28534
251 + 28283 = 28534
257 + 28277 = 28534

Showing the first eight; more decompositions exist.
