Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33563728, here are decompositions:

71 + 33563657 = 33563728
227 + 33563501 = 33563728
257 + 33563471 = 33563728
269 + 33563459 = 33563728
281 + 33563447 = 33563728
347 + 33563381 = 33563728
389 + 33563339 = 33563728
461 + 33563267 = 33563728

Showing the first eight; more decompositions exist.
