Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28300, here are decompositions:

3 + 28297 = 28300
11 + 28289 = 28300
17 + 28283 = 28300
23 + 28277 = 28300
71 + 28229 = 28300
89 + 28211 = 28300
137 + 28163 = 28300
149 + 28151 = 28300

Showing the first eight; more decompositions exist.
