Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8286, here are decompositions:

13 + 8273 = 8286
17 + 8269 = 8286
23 + 8263 = 8286
43 + 8243 = 8286
53 + 8233 = 8286
67 + 8219 = 8286
107 + 8179 = 8286
139 + 8147 = 8286

Showing the first eight; more decompositions exist.
