Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561740, here are decompositions:

61 + 33561679 = 33561740
67 + 33561673 = 33561740
181 + 33561559 = 33561740
271 + 33561469 = 33561740
379 + 33561361 = 33561740
397 + 33561343 = 33561740
547 + 33561193 = 33561740
571 + 33561169 = 33561740

Showing the first eight; more decompositions exist.
