Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8288, here are decompositions:

19 + 8269 = 8288
67 + 8221 = 8288
79 + 8209 = 8288
97 + 8191 = 8288
109 + 8179 = 8288
127 + 8161 = 8288
199 + 8089 = 8288
229 + 8059 = 8288

Showing the first eight; more decompositions exist.
