Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33520800, here are decompositions:

17 + 33520783 = 33520800
23 + 33520777 = 33520800
37 + 33520763 = 33520800
41 + 33520759 = 33520800
113 + 33520687 = 33520800
151 + 33520649 = 33520800
179 + 33520621 = 33520800
197 + 33520603 = 33520800

Showing the first eight; more decompositions exist.
