Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521418, here are decompositions:

17 + 33521401 = 33521418
97 + 33521321 = 33521418
181 + 33521237 = 33521418
197 + 33521221 = 33521418
199 + 33521219 = 33521418
239 + 33521179 = 33521418
241 + 33521177 = 33521418
277 + 33521141 = 33521418

Showing the first eight; more decompositions exist.
