Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572768, here are decompositions:

67 + 33572701 = 33572768
139 + 33572629 = 33572768
211 + 33572557 = 33572768
241 + 33572527 = 33572768
421 + 33572347 = 33572768
457 + 33572311 = 33572768
577 + 33572191 = 33572768
727 + 33572041 = 33572768

Showing the first eight; more decompositions exist.
