Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561366, here are decompositions:

5 + 33561361 = 33561366
23 + 33561343 = 33561366
79 + 33561287 = 33561366
103 + 33561263 = 33561366
173 + 33561193 = 33561366
193 + 33561173 = 33561366
197 + 33561169 = 33561366
227 + 33561139 = 33561366

Showing the first eight; more decompositions exist.
