Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561560, here are decompositions:

3 + 33561557 = 33561560
181 + 33561379 = 33561560
199 + 33561361 = 33561560
367 + 33561193 = 33561560
379 + 33561181 = 33561560
421 + 33561139 = 33561560
457 + 33561103 = 33561560
541 + 33561019 = 33561560

Showing the first eight; more decompositions exist.
