Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561638, here are decompositions:

31 + 33561607 = 33561638
67 + 33561571 = 33561638
79 + 33561559 = 33561638
277 + 33561361 = 33561638
367 + 33561271 = 33561638
457 + 33561181 = 33561638
499 + 33561139 = 33561638
571 + 33561067 = 33561638

Showing the first eight; more decompositions exist.
