Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8208, here are decompositions:

17 + 8191 = 8208
29 + 8179 = 8208
37 + 8171 = 8208
41 + 8167 = 8208
47 + 8161 = 8208
61 + 8147 = 8208
97 + 8111 = 8208
107 + 8101 = 8208

Showing the first eight; more decompositions exist.
