Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521728, here are decompositions:

17 + 33521711 = 33521728
179 + 33521549 = 33521728
197 + 33521531 = 33521728
257 + 33521471 = 33521728
311 + 33521417 = 33521728
491 + 33521237 = 33521728
509 + 33521219 = 33521728
557 + 33521171 = 33521728

Showing the first eight; more decompositions exist.
