Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33525440, here are decompositions:

7 + 33525433 = 33525440
61 + 33525379 = 33525440
79 + 33525361 = 33525440
127 + 33525313 = 33525440
241 + 33525199 = 33525440
349 + 33525091 = 33525440
379 + 33525061 = 33525440
463 + 33524977 = 33525440

Showing the first eight; more decompositions exist.
