Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561632, here are decompositions:

61 + 33561571 = 33561632
73 + 33561559 = 33561632
163 + 33561469 = 33561632
271 + 33561361 = 33561632
439 + 33561193 = 33561632
463 + 33561169 = 33561632
613 + 33561019 = 33561632
619 + 33561013 = 33561632

Showing the first eight; more decompositions exist.
