Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33541920, here are decompositions:

11 + 33541909 = 33541920
59 + 33541861 = 33541920
67 + 33541853 = 33541920
101 + 33541819 = 33541920
103 + 33541817 = 33541920
149 + 33541771 = 33541920
151 + 33541769 = 33541920
163 + 33541757 = 33541920

Showing the first eight; more decompositions exist.
