Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28510, here are decompositions:

11 + 28499 = 28510
17 + 28493 = 28510
47 + 28463 = 28510
71 + 28439 = 28510
101 + 28409 = 28510
107 + 28403 = 28510
191 + 28319 = 28510
227 + 28283 = 28510

Showing the first eight; more decompositions exist.
