Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8184, here are decompositions:

5 + 8179 = 8184
13 + 8171 = 8184
17 + 8167 = 8184
23 + 8161 = 8184
37 + 8147 = 8184
61 + 8123 = 8184
67 + 8117 = 8184
73 + 8111 = 8184

Showing the first eight; more decompositions exist.
