Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33525978, here are decompositions:

29 + 33525949 = 33525978
47 + 33525931 = 33525978
61 + 33525917 = 33525978
89 + 33525889 = 33525978
107 + 33525871 = 33525978
127 + 33525851 = 33525978
251 + 33525727 = 33525978
271 + 33525707 = 33525978

Showing the first eight; more decompositions exist.
