Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28328, here are decompositions:

19 + 28309 = 28328
31 + 28297 = 28328
109 + 28219 = 28328
127 + 28201 = 28328
229 + 28099 = 28328
241 + 28087 = 28328
271 + 28057 = 28328
277 + 28051 = 28328

Showing the first eight; more decompositions exist.
