Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28416, here are decompositions:

5 + 28411 = 28416
7 + 28409 = 28416
13 + 28403 = 28416
23 + 28393 = 28416
29 + 28387 = 28416
67 + 28349 = 28416
97 + 28319 = 28416
107 + 28309 = 28416

Showing the first eight; more decompositions exist.
