Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28396, here are decompositions:

3 + 28393 = 28396
47 + 28349 = 28396
89 + 28307 = 28396
107 + 28289 = 28396
113 + 28283 = 28396
167 + 28229 = 28396
233 + 28163 = 28396
443 + 27953 = 28396

Showing the first eight; more decompositions exist.
