Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521656, here are decompositions:

107 + 33521549 = 33521656
173 + 33521483 = 33521656
239 + 33521417 = 33521656
263 + 33521393 = 33521656
419 + 33521237 = 33521656
479 + 33521177 = 33521656
557 + 33521099 = 33521656
569 + 33521087 = 33521656

Showing the first eight; more decompositions exist.
