Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28298, here are decompositions:

19 + 28279 = 28298
79 + 28219 = 28298
97 + 28201 = 28298
199 + 28099 = 28298
211 + 28087 = 28298
229 + 28069 = 28298
241 + 28057 = 28298
271 + 28027 = 28298

Showing the first eight; more decompositions exist.
