Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28398, here are decompositions:

5 + 28393 = 28398
11 + 28387 = 28398
47 + 28351 = 28398
79 + 28319 = 28398
89 + 28309 = 28398
101 + 28297 = 28398
109 + 28289 = 28398
179 + 28219 = 28398

Showing the first eight; more decompositions exist.
