Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561572, here are decompositions:

13 + 33561559 = 33561572
103 + 33561469 = 33561572
193 + 33561379 = 33561572
211 + 33561361 = 33561572
229 + 33561343 = 33561572
379 + 33561193 = 33561572
433 + 33561139 = 33561572
643 + 33560929 = 33561572

Showing the first eight; more decompositions exist.
