Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8164, here are decompositions:

3 + 8161 = 8164
17 + 8147 = 8164
41 + 8123 = 8164
47 + 8117 = 8164
53 + 8111 = 8164
71 + 8093 = 8164
83 + 8081 = 8164
227 + 7937 = 8164

Showing the first eight; more decompositions exist.
