Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33543872, here are decompositions:

31 + 33543841 = 33543872
163 + 33543709 = 33543872
199 + 33543673 = 33543872
211 + 33543661 = 33543872
223 + 33543649 = 33543872
433 + 33543439 = 33543872
499 + 33543373 = 33543872
541 + 33543331 = 33543872

Showing the first eight; more decompositions exist.
