Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33605180, here are decompositions:

3 + 33605177 = 33605180
31 + 33605149 = 33605180
43 + 33605137 = 33605180
139 + 33605041 = 33605180
163 + 33605017 = 33605180
211 + 33604969 = 33605180
307 + 33604873 = 33605180
523 + 33604657 = 33605180

Showing the first eight; more decompositions exist.
