Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8168, here are decompositions:

7 + 8161 = 8168
67 + 8101 = 8168
79 + 8089 = 8168
109 + 8059 = 8168
151 + 8017 = 8168
157 + 8011 = 8168
241 + 7927 = 8168
379 + 7789 = 8168

Showing the first eight; more decompositions exist.
