Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166676, here are decompositions:

7 + 166669 = 166676
19 + 166657 = 166676
67 + 166609 = 166676
73 + 166603 = 166676
79 + 166597 = 166676
109 + 166567 = 166676
277 + 166399 = 166676
283 + 166393 = 166676

Showing the first eight; more decompositions exist.
