Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28460, here are decompositions:

13 + 28447 = 28460
31 + 28429 = 28460
67 + 28393 = 28460
73 + 28387 = 28460
109 + 28351 = 28460
151 + 28309 = 28460
163 + 28297 = 28460
181 + 28279 = 28460

Showing the first eight; more decompositions exist.
