Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13066, here are decompositions:

3 + 13063 = 13066
17 + 13049 = 13066
23 + 13043 = 13066
29 + 13037 = 13066
59 + 13007 = 13066
83 + 12983 = 13066
107 + 12959 = 13066
113 + 12953 = 13066

Showing the first eight; more decompositions exist.
