Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28288, here are decompositions:

5 + 28283 = 28288
11 + 28277 = 28288
59 + 28229 = 28288
107 + 28181 = 28288
137 + 28151 = 28288
179 + 28109 = 28288
191 + 28097 = 28288
257 + 28031 = 28288

Showing the first eight; more decompositions exist.
