Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561818, here are decompositions:

19 + 33561799 = 33561818
67 + 33561751 = 33561818
139 + 33561679 = 33561818
211 + 33561607 = 33561818
349 + 33561469 = 33561818
439 + 33561379 = 33561818
457 + 33561361 = 33561818
547 + 33561271 = 33561818

Showing the first eight; more decompositions exist.
