Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166664, here are decompositions:

7 + 166657 = 166664
37 + 166627 = 166664
61 + 166603 = 166664
67 + 166597 = 166664
97 + 166567 = 166664
103 + 166561 = 166664
193 + 166471 = 166664
271 + 166393 = 166664

Showing the first eight; more decompositions exist.
