Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521686, here are decompositions:

137 + 33521549 = 33521686
269 + 33521417 = 33521686
293 + 33521393 = 33521686
449 + 33521237 = 33521686
467 + 33521219 = 33521686
509 + 33521177 = 33521686
587 + 33521099 = 33521686
599 + 33521087 = 33521686

Showing the first eight; more decompositions exist.
