Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8398, here are decompositions:

11 + 8387 = 8398
29 + 8369 = 8398
101 + 8297 = 8398
107 + 8291 = 8398
167 + 8231 = 8398
179 + 8219 = 8398
227 + 8171 = 8398
251 + 8147 = 8398

Showing the first eight; more decompositions exist.
