Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8166, here are decompositions:

5 + 8161 = 8166
19 + 8147 = 8166
43 + 8123 = 8166
73 + 8093 = 8166
79 + 8087 = 8166
97 + 8069 = 8166
107 + 8059 = 8166
113 + 8053 = 8166

Showing the first eight; more decompositions exist.
