Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33571872, here are decompositions:

23 + 33571849 = 33571872
41 + 33571831 = 33571872
43 + 33571829 = 33571872
53 + 33571819 = 33571872
71 + 33571801 = 33571872
79 + 33571793 = 33571872
149 + 33571723 = 33571872
151 + 33571721 = 33571872

Showing the first eight; more decompositions exist.
