Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33525820, here are decompositions:

17 + 33525803 = 33525820
47 + 33525773 = 33525820
89 + 33525731 = 33525820
113 + 33525707 = 33525820
173 + 33525647 = 33525820
179 + 33525641 = 33525820
227 + 33525593 = 33525820
269 + 33525551 = 33525820

Showing the first eight; more decompositions exist.
