Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28494, here are decompositions:

17 + 28477 = 28494
31 + 28463 = 28494
47 + 28447 = 28494
61 + 28433 = 28494
83 + 28411 = 28494
101 + 28393 = 28494
107 + 28387 = 28494
197 + 28297 = 28494

Showing the first eight; more decompositions exist.
