Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33528872, here are decompositions:

31 + 33528841 = 33528872
43 + 33528829 = 33528872
79 + 33528793 = 33528872
103 + 33528769 = 33528872
151 + 33528721 = 33528872
193 + 33528679 = 33528872
241 + 33528631 = 33528872
373 + 33528499 = 33528872

Showing the first eight; more decompositions exist.
