Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28330, here are decompositions:

11 + 28319 = 28330
23 + 28307 = 28330
41 + 28289 = 28330
47 + 28283 = 28330
53 + 28277 = 28330
101 + 28229 = 28330
149 + 28181 = 28330
167 + 28163 = 28330

Showing the first eight; more decompositions exist.
