Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28310, here are decompositions:

3 + 28307 = 28310
13 + 28297 = 28310
31 + 28279 = 28310
109 + 28201 = 28310
127 + 28183 = 28310
199 + 28111 = 28310
211 + 28099 = 28310
223 + 28087 = 28310

Showing the first eight; more decompositions exist.
