Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561860, here are decompositions:

43 + 33561817 = 33561860
61 + 33561799 = 33561860
109 + 33561751 = 33561860
181 + 33561679 = 33561860
499 + 33561361 = 33561860
691 + 33561169 = 33561860
757 + 33561103 = 33561860
853 + 33561007 = 33561860

Showing the first eight; more decompositions exist.
