Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33605820, here are decompositions:

13 + 33605807 = 33605820
23 + 33605797 = 33605820
71 + 33605749 = 33605820
97 + 33605723 = 33605820
103 + 33605717 = 33605820
107 + 33605713 = 33605820
137 + 33605683 = 33605820
151 + 33605669 = 33605820

Showing the first eight; more decompositions exist.
