Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33525120, here are decompositions:

29 + 33525091 = 33525120
43 + 33525077 = 33525120
59 + 33525061 = 33525120
61 + 33525059 = 33525120
71 + 33525049 = 33525120
103 + 33525017 = 33525120
107 + 33525013 = 33525120
149 + 33524971 = 33525120

Showing the first eight; more decompositions exist.
