Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28386, here are decompositions:

37 + 28349 = 28386
67 + 28319 = 28386
79 + 28307 = 28386
89 + 28297 = 28386
97 + 28289 = 28386
103 + 28283 = 28386
107 + 28279 = 28386
109 + 28277 = 28386

Showing the first eight; more decompositions exist.
