Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166682, here are decompositions:

3 + 166679 = 166682
13 + 166669 = 166682
73 + 166609 = 166682
79 + 166603 = 166682
211 + 166471 = 166682
283 + 166399 = 166682
331 + 166351 = 166682
379 + 166303 = 166682

Showing the first eight; more decompositions exist.
