Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561390, here are decompositions:

11 + 33561379 = 33561390
29 + 33561361 = 33561390
47 + 33561343 = 33561390
103 + 33561287 = 33561390
127 + 33561263 = 33561390
193 + 33561197 = 33561390
197 + 33561193 = 33561390
199 + 33561191 = 33561390

Showing the first eight; more decompositions exist.
