Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572918, here are decompositions:

7 + 33572911 = 33572918
37 + 33572881 = 33572918
61 + 33572857 = 33572918
139 + 33572779 = 33572918
271 + 33572647 = 33572918
397 + 33572521 = 33572918
541 + 33572377 = 33572918
571 + 33572347 = 33572918

Showing the first eight; more decompositions exist.
