Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521566, here are decompositions:

17 + 33521549 = 33521566
83 + 33521483 = 33521566
149 + 33521417 = 33521566
173 + 33521393 = 33521566
347 + 33521219 = 33521566
389 + 33521177 = 33521566
467 + 33521099 = 33521566
479 + 33521087 = 33521566

Showing the first eight; more decompositions exist.
