Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66012, here are decompositions:

19 + 65993 = 66012
29 + 65983 = 66012
31 + 65981 = 66012
61 + 65951 = 66012
83 + 65929 = 66012
113 + 65899 = 66012
131 + 65881 = 66012
173 + 65839 = 66012

Showing the first eight; more decompositions exist.
