Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28404, here are decompositions:

11 + 28393 = 28404
17 + 28387 = 28404
53 + 28351 = 28404
97 + 28307 = 28404
107 + 28297 = 28404
127 + 28277 = 28404
193 + 28211 = 28404
223 + 28181 = 28404

Showing the first eight; more decompositions exist.
