Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561550, here are decompositions:

17 + 33561533 = 33561550
23 + 33561527 = 33561550
47 + 33561503 = 33561550
137 + 33561413 = 33561550
263 + 33561287 = 33561550
353 + 33561197 = 33561550
359 + 33561191 = 33561550
389 + 33561161 = 33561550

Showing the first eight; more decompositions exist.
