Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33605390, here are decompositions:

3 + 33605387 = 33605390
97 + 33605293 = 33605390
127 + 33605263 = 33605390
139 + 33605251 = 33605390
163 + 33605227 = 33605390
193 + 33605197 = 33605390
241 + 33605149 = 33605390
349 + 33605041 = 33605390

Showing the first eight; more decompositions exist.
