Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33525818, here are decompositions:

61 + 33525757 = 33525818
127 + 33525691 = 33525818
199 + 33525619 = 33525818
211 + 33525607 = 33525818
331 + 33525487 = 33525818
379 + 33525439 = 33525818
439 + 33525379 = 33525818
457 + 33525361 = 33525818

Showing the first eight; more decompositions exist.
