Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66066, here are decompositions:

19 + 66047 = 66066
29 + 66037 = 66066
37 + 66029 = 66066
73 + 65993 = 66066
83 + 65983 = 66066
103 + 65963 = 66066
109 + 65957 = 66066
137 + 65929 = 66066

Showing the first eight; more decompositions exist.
