Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8160, here are decompositions:

13 + 8147 = 8160
37 + 8123 = 8160
43 + 8117 = 8160
59 + 8101 = 8160
67 + 8093 = 8160
71 + 8089 = 8160
73 + 8087 = 8160
79 + 8081 = 8160

Showing the first eight; more decompositions exist.
