Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33605420, here are decompositions:

3 + 33605417 = 33605420
31 + 33605389 = 33605420
127 + 33605293 = 33605420
151 + 33605269 = 33605420
157 + 33605263 = 33605420
193 + 33605227 = 33605420
223 + 33605197 = 33605420
271 + 33605149 = 33605420

Showing the first eight; more decompositions exist.
