Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33528840, here are decompositions:

11 + 33528829 = 33528840
17 + 33528823 = 33528840
19 + 33528821 = 33528840
43 + 33528797 = 33528840
47 + 33528793 = 33528840
71 + 33528769 = 33528840
73 + 33528767 = 33528840
89 + 33528751 = 33528840

Showing the first eight; more decompositions exist.
