Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66636, here are decompositions:

7 + 66629 = 66636
19 + 66617 = 66636
43 + 66593 = 66636
67 + 66569 = 66636
83 + 66553 = 66636
103 + 66533 = 66636
107 + 66529 = 66636
113 + 66523 = 66636

Showing the first eight; more decompositions exist.
