Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166554, here are decompositions:

13 + 166541 = 166554
67 + 166487 = 166554
83 + 166471 = 166554
97 + 166457 = 166554
137 + 166417 = 166554
151 + 166403 = 166554
191 + 166363 = 166554
197 + 166357 = 166554

Showing the first eight; more decompositions exist.
