Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561420, here are decompositions:

7 + 33561413 = 33561420
31 + 33561389 = 33561420
41 + 33561379 = 33561420
59 + 33561361 = 33561420
149 + 33561271 = 33561420
157 + 33561263 = 33561420
223 + 33561197 = 33561420
227 + 33561193 = 33561420

Showing the first eight; more decompositions exist.
