Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561938, here are decompositions:

19 + 33561919 = 33561938
61 + 33561877 = 33561938
139 + 33561799 = 33561938
331 + 33561607 = 33561938
367 + 33561571 = 33561938
379 + 33561559 = 33561938
577 + 33561361 = 33561938
757 + 33561181 = 33561938

Showing the first eight; more decompositions exist.
