Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572144, here are decompositions:

3 + 33572141 = 33572144
13 + 33572131 = 33572144
61 + 33572083 = 33572144
103 + 33572041 = 33572144
181 + 33571963 = 33572144
211 + 33571933 = 33572144
271 + 33571873 = 33572144
313 + 33571831 = 33572144

Showing the first eight; more decompositions exist.
