Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521616, here are decompositions:

67 + 33521549 = 33521616
179 + 33521437 = 33521616
199 + 33521417 = 33521616
223 + 33521393 = 33521616
379 + 33521237 = 33521616
397 + 33521219 = 33521616
439 + 33521177 = 33521616
577 + 33521039 = 33521616

Showing the first eight; more decompositions exist.
