Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33525728, here are decompositions:

37 + 33525691 = 33525728
109 + 33525619 = 33525728
157 + 33525571 = 33525728
199 + 33525529 = 33525728
211 + 33525517 = 33525728
241 + 33525487 = 33525728
349 + 33525379 = 33525728
367 + 33525361 = 33525728

Showing the first eight; more decompositions exist.
