Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66164, here are decompositions:

3 + 66161 = 66164
61 + 66103 = 66164
97 + 66067 = 66164
127 + 66037 = 66164
181 + 65983 = 66164
283 + 65881 = 66164
313 + 65851 = 66164
337 + 65827 = 66164

Showing the first eight; more decompositions exist.
