Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33525018, here are decompositions:

5 + 33525013 = 33525018
19 + 33524999 = 33525018
41 + 33524977 = 33525018
47 + 33524971 = 33525018
67 + 33524951 = 33525018
127 + 33524891 = 33525018
199 + 33524819 = 33525018
229 + 33524789 = 33525018

Showing the first eight; more decompositions exist.
