Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572040, here are decompositions:

11 + 33572029 = 33572040
13 + 33572027 = 33572040
31 + 33572009 = 33572040
43 + 33571997 = 33572040
97 + 33571943 = 33572040
101 + 33571939 = 33572040
107 + 33571933 = 33572040
109 + 33571931 = 33572040

Showing the first eight; more decompositions exist.
