Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28368, here are decompositions:

17 + 28351 = 28368
19 + 28349 = 28368
59 + 28309 = 28368
61 + 28307 = 28368
71 + 28297 = 28368
79 + 28289 = 28368
89 + 28279 = 28368
139 + 28229 = 28368

Showing the first eight; more decompositions exist.
