Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33525520, here are decompositions:

3 + 33525517 = 33525520
29 + 33525491 = 33525520
71 + 33525449 = 33525520
179 + 33525341 = 33525520
233 + 33525287 = 33525520
239 + 33525281 = 33525520
263 + 33525257 = 33525520
293 + 33525227 = 33525520

Showing the first eight; more decompositions exist.
