Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33605220, here are decompositions:

13 + 33605207 = 33605220
23 + 33605197 = 33605220
43 + 33605177 = 33605220
67 + 33605153 = 33605220
71 + 33605149 = 33605220
83 + 33605137 = 33605220
179 + 33605041 = 33605220
227 + 33604993 = 33605220

Showing the first eight; more decompositions exist.
