Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42066, here are decompositions:

5 + 42061 = 42066
23 + 42043 = 42066
43 + 42023 = 42066
47 + 42019 = 42066
53 + 42013 = 42066
67 + 41999 = 42066
83 + 41983 = 42066
97 + 41969 = 42066

Showing the first eight; more decompositions exist.
