Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33525540, here are decompositions:

7 + 33525533 = 33525540
11 + 33525529 = 33525540
23 + 33525517 = 33525540
53 + 33525487 = 33525540
101 + 33525439 = 33525540
107 + 33525433 = 33525540
179 + 33525361 = 33525540
199 + 33525341 = 33525540

Showing the first eight; more decompositions exist.
