Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557638, here are decompositions:

11 + 33557627 = 33557638
41 + 33557597 = 33557638
71 + 33557567 = 33557638
167 + 33557471 = 33557638
227 + 33557411 = 33557638
239 + 33557399 = 33557638
251 + 33557387 = 33557638
281 + 33557357 = 33557638

Showing the first eight; more decompositions exist.
