Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28360, here are decompositions:

11 + 28349 = 28360
41 + 28319 = 28360
53 + 28307 = 28360
71 + 28289 = 28360
83 + 28277 = 28360
131 + 28229 = 28360
149 + 28211 = 28360
179 + 28181 = 28360

Showing the first eight; more decompositions exist.
