Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33605680, here are decompositions:

11 + 33605669 = 33605680
89 + 33605591 = 33605680
113 + 33605567 = 33605680
137 + 33605543 = 33605680
149 + 33605531 = 33605680
239 + 33605441 = 33605680
263 + 33605417 = 33605680
293 + 33605387 = 33605680

Showing the first eight; more decompositions exist.
