Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572238, here are decompositions:

19 + 33572219 = 33572238
47 + 33572191 = 33572238
97 + 33572141 = 33572238
107 + 33572131 = 33572238
157 + 33572081 = 33572238
197 + 33572041 = 33572238
211 + 33572027 = 33572238
229 + 33572009 = 33572238

Showing the first eight; more decompositions exist.
