Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33605772, here are decompositions:

23 + 33605749 = 33605772
43 + 33605729 = 33605772
59 + 33605713 = 33605772
71 + 33605701 = 33605772
89 + 33605683 = 33605772
103 + 33605669 = 33605772
181 + 33605591 = 33605772
229 + 33605543 = 33605772

Showing the first eight; more decompositions exist.
