Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521448, here are decompositions:

11 + 33521437 = 33521448
17 + 33521431 = 33521448
31 + 33521417 = 33521448
47 + 33521401 = 33521448
127 + 33521321 = 33521448
211 + 33521237 = 33521448
227 + 33521221 = 33521448
229 + 33521219 = 33521448

Showing the first eight; more decompositions exist.
