Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168166, here are decompositions:

23 + 168143 = 168166
83 + 168083 = 168166
137 + 168029 = 168166
179 + 167987 = 168166
293 + 167873 = 168166
389 + 167777 = 168166
419 + 167747 = 168166
503 + 167663 = 168166

Showing the first eight; more decompositions exist.
