Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20166, here are decompositions:

5 + 20161 = 20166
17 + 20149 = 20166
19 + 20147 = 20166
23 + 20143 = 20166
37 + 20129 = 20166
43 + 20123 = 20166
53 + 20113 = 20166
59 + 20107 = 20166

Showing the first eight; more decompositions exist.
