Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561760, here are decompositions:

17 + 33561743 = 33561760
41 + 33561719 = 33561760
107 + 33561653 = 33561760
149 + 33561611 = 33561760
227 + 33561533 = 33561760
233 + 33561527 = 33561760
257 + 33561503 = 33561760
347 + 33561413 = 33561760

Showing the first eight; more decompositions exist.
