Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505872, here are decompositions:

5 + 33505867 = 33505872
13 + 33505859 = 33505872
19 + 33505853 = 33505872
73 + 33505799 = 33505872
83 + 33505789 = 33505872
149 + 33505723 = 33505872
241 + 33505631 = 33505872
251 + 33505621 = 33505872

Showing the first eight; more decompositions exist.
