Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7066, here are decompositions:

23 + 7043 = 7066
47 + 7019 = 7066
53 + 7013 = 7066
83 + 6983 = 7066
89 + 6977 = 7066
107 + 6959 = 7066
149 + 6917 = 7066
167 + 6899 = 7066

Showing the first eight; more decompositions exist.
