Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561408, here are decompositions:

19 + 33561389 = 33561408
29 + 33561379 = 33561408
47 + 33561361 = 33561408
137 + 33561271 = 33561408
211 + 33561197 = 33561408
227 + 33561181 = 33561408
239 + 33561169 = 33561408
269 + 33561139 = 33561408

Showing the first eight; more decompositions exist.
