Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33605442, here are decompositions:

23 + 33605419 = 33605442
53 + 33605389 = 33605442
149 + 33605293 = 33605442
151 + 33605291 = 33605442
173 + 33605269 = 33605442
179 + 33605263 = 33605442
191 + 33605251 = 33605442
223 + 33605219 = 33605442

Showing the first eight; more decompositions exist.
