Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33567872, here are decompositions:

73 + 33567799 = 33567872
193 + 33567679 = 33567872
241 + 33567631 = 33567872
271 + 33567601 = 33567872
601 + 33567271 = 33567872
619 + 33567253 = 33567872
631 + 33567241 = 33567872
643 + 33567229 = 33567872

Showing the first eight; more decompositions exist.
