Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28504, here are decompositions:

5 + 28499 = 28504
11 + 28493 = 28504
41 + 28463 = 28504
71 + 28433 = 28504
101 + 28403 = 28504
197 + 28307 = 28504
227 + 28277 = 28504
293 + 28211 = 28504

Showing the first eight; more decompositions exist.
