Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491080, here are decompositions:

17 + 33491063 = 33491080
23 + 33491057 = 33491080
83 + 33490997 = 33491080
89 + 33490991 = 33491080
131 + 33490949 = 33491080
173 + 33490907 = 33491080
191 + 33490889 = 33491080
239 + 33490841 = 33491080

Showing the first eight; more decompositions exist.
