Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28304, here are decompositions:

7 + 28297 = 28304
103 + 28201 = 28304
181 + 28123 = 28304
193 + 28111 = 28304
223 + 28081 = 28304
277 + 28027 = 28304
307 + 27997 = 28304
337 + 27967 = 28304

Showing the first eight; more decompositions exist.
