Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572180, here are decompositions:

7 + 33572173 = 33572180
97 + 33572083 = 33572180
139 + 33572041 = 33572180
151 + 33572029 = 33572180
241 + 33571939 = 33572180
307 + 33571873 = 33572180
331 + 33571849 = 33572180
349 + 33571831 = 33572180

Showing the first eight; more decompositions exist.
