Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33525218, here are decompositions:

19 + 33525199 = 33525218
37 + 33525181 = 33525218
127 + 33525091 = 33525218
157 + 33525061 = 33525218
241 + 33524977 = 33525218
409 + 33524809 = 33525218
499 + 33524719 = 33525218
577 + 33524641 = 33525218

Showing the first eight; more decompositions exist.
