Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513666, here are decompositions:

5 + 33513661 = 33513666
7 + 33513659 = 33513666
37 + 33513629 = 33513666
97 + 33513569 = 33513666
107 + 33513559 = 33513666
127 + 33513539 = 33513666
157 + 33513509 = 33513666
163 + 33513503 = 33513666

Showing the first eight; more decompositions exist.
