Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572898, here are decompositions:

17 + 33572881 = 33572898
41 + 33572857 = 33572898
71 + 33572827 = 33572898
157 + 33572741 = 33572898
197 + 33572701 = 33572898
199 + 33572699 = 33572898
211 + 33572687 = 33572898
251 + 33572647 = 33572898

Showing the first eight; more decompositions exist.
