Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33545808, here are decompositions:

5 + 33545803 = 33545808
19 + 33545789 = 33545808
61 + 33545747 = 33545808
151 + 33545657 = 33545808
157 + 33545651 = 33545808
199 + 33545609 = 33545808
211 + 33545597 = 33545808
229 + 33545579 = 33545808

Showing the first eight; more decompositions exist.
