Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166026, here are decompositions:

5 + 166021 = 166026
13 + 166013 = 166026
43 + 165983 = 166026
79 + 165947 = 166026
139 + 165887 = 166026
149 + 165877 = 166026
193 + 165833 = 166026
197 + 165829 = 166026

Showing the first eight; more decompositions exist.
