Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33525290, here are decompositions:

3 + 33525287 = 33525290
67 + 33525223 = 33525290
109 + 33525181 = 33525290
199 + 33525091 = 33525290
229 + 33525061 = 33525290
241 + 33525049 = 33525290
277 + 33525013 = 33525290
313 + 33524977 = 33525290

Showing the first eight; more decompositions exist.
