Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561440, here are decompositions:

61 + 33561379 = 33561440
79 + 33561361 = 33561440
97 + 33561343 = 33561440
271 + 33561169 = 33561440
337 + 33561103 = 33561440
373 + 33561067 = 33561440
421 + 33561019 = 33561440
433 + 33561007 = 33561440

Showing the first eight; more decompositions exist.
