Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8178, here are decompositions:

7 + 8171 = 8178
11 + 8167 = 8178
17 + 8161 = 8178
31 + 8147 = 8178
61 + 8117 = 8178
67 + 8111 = 8178
89 + 8089 = 8178
97 + 8081 = 8178

Showing the first eight; more decompositions exist.
