Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513780, here are decompositions:

19 + 33513761 = 33513780
67 + 33513713 = 33513780
73 + 33513707 = 33513780
107 + 33513673 = 33513780
149 + 33513631 = 33513780
151 + 33513629 = 33513780
199 + 33513581 = 33513780
211 + 33513569 = 33513780

Showing the first eight; more decompositions exist.
