Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77166, here are decompositions:

13 + 77153 = 77166
29 + 77137 = 77166
73 + 77093 = 77166
97 + 77069 = 77166
137 + 77029 = 77166
149 + 77017 = 77166
163 + 77003 = 77166
223 + 76943 = 77166

Showing the first eight; more decompositions exist.
