Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66166, here are decompositions:

5 + 66161 = 66166
29 + 66137 = 66166
59 + 66107 = 66166
83 + 66083 = 66166
137 + 66029 = 66166
173 + 65993 = 66166
239 + 65927 = 66166
389 + 65777 = 66166

Showing the first eight; more decompositions exist.
