Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572942, here are decompositions:

31 + 33572911 = 33572942
61 + 33572881 = 33572942
79 + 33572863 = 33572942
163 + 33572779 = 33572942
199 + 33572743 = 33572942
229 + 33572713 = 33572942
241 + 33572701 = 33572942
313 + 33572629 = 33572942

Showing the first eight; more decompositions exist.
