Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33605406, here are decompositions:

13 + 33605393 = 33605406
17 + 33605389 = 33605406
19 + 33605387 = 33605406
97 + 33605309 = 33605406
113 + 33605293 = 33605406
137 + 33605269 = 33605406
139 + 33605267 = 33605406
179 + 33605227 = 33605406

Showing the first eight; more decompositions exist.
