Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33528572, here are decompositions:

61 + 33528511 = 33528572
73 + 33528499 = 33528572
109 + 33528463 = 33528572
199 + 33528373 = 33528572
211 + 33528361 = 33528572
283 + 33528289 = 33528572
331 + 33528241 = 33528572
379 + 33528193 = 33528572

Showing the first eight; more decompositions exist.
