Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561450, here are decompositions:

37 + 33561413 = 33561450
61 + 33561389 = 33561450
71 + 33561379 = 33561450
89 + 33561361 = 33561450
107 + 33561343 = 33561450
163 + 33561287 = 33561450
179 + 33561271 = 33561450
257 + 33561193 = 33561450

Showing the first eight; more decompositions exist.
