Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572820, here are decompositions:

7 + 33572813 = 33572820
41 + 33572779 = 33572820
79 + 33572741 = 33572820
107 + 33572713 = 33572820
137 + 33572683 = 33572820
173 + 33572647 = 33572820
191 + 33572629 = 33572820
263 + 33572557 = 33572820

Showing the first eight; more decompositions exist.
