Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33525648, here are decompositions:

5 + 33525643 = 33525648
7 + 33525641 = 33525648
29 + 33525619 = 33525648
41 + 33525607 = 33525648
97 + 33525551 = 33525648
131 + 33525517 = 33525648
157 + 33525491 = 33525648
199 + 33525449 = 33525648

Showing the first eight; more decompositions exist.
