Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513808, here are decompositions:

11 + 33513797 = 33513808
47 + 33513761 = 33513808
101 + 33513707 = 33513808
149 + 33513659 = 33513808
179 + 33513629 = 33513808
197 + 33513611 = 33513808
227 + 33513581 = 33513808
239 + 33513569 = 33513808

Showing the first eight; more decompositions exist.
