Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572028, here are decompositions:

19 + 33572009 = 33572028
31 + 33571997 = 33572028
89 + 33571939 = 33572028
97 + 33571931 = 33572028
179 + 33571849 = 33572028
197 + 33571831 = 33572028
199 + 33571829 = 33572028
211 + 33571817 = 33572028

Showing the first eight; more decompositions exist.
