Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572020, here are decompositions:

11 + 33572009 = 33572020
23 + 33571997 = 33572020
89 + 33571931 = 33572020
191 + 33571829 = 33572020
197 + 33571823 = 33572020
227 + 33571793 = 33572020
281 + 33571739 = 33572020
311 + 33571709 = 33572020

Showing the first eight; more decompositions exist.
