Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33605240, here are decompositions:

13 + 33605227 = 33605240
43 + 33605197 = 33605240
103 + 33605137 = 33605240
199 + 33605041 = 33605240
223 + 33605017 = 33605240
271 + 33604969 = 33605240
307 + 33604933 = 33605240
367 + 33604873 = 33605240

Showing the first eight; more decompositions exist.
