Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126066, here are decompositions:

19 + 126047 = 126066
29 + 126037 = 126066
43 + 126023 = 126066
47 + 126019 = 126066
53 + 126013 = 126066
103 + 125963 = 126066
107 + 125959 = 126066
137 + 125929 = 126066

Showing the first eight; more decompositions exist.
