Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33605740, here are decompositions:

11 + 33605729 = 33605740
17 + 33605723 = 33605740
23 + 33605717 = 33605740
71 + 33605669 = 33605740
149 + 33605591 = 33605740
173 + 33605567 = 33605740
197 + 33605543 = 33605740
347 + 33605393 = 33605740

Showing the first eight; more decompositions exist.
