Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33525180, here are decompositions:

43 + 33525137 = 33525180
89 + 33525091 = 33525180
103 + 33525077 = 33525180
131 + 33525049 = 33525180
163 + 33525017 = 33525180
167 + 33525013 = 33525180
181 + 33524999 = 33525180
229 + 33524951 = 33525180

Showing the first eight; more decompositions exist.
