Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33605440, here are decompositions:

23 + 33605417 = 33605440
47 + 33605393 = 33605440
53 + 33605387 = 33605440
131 + 33605309 = 33605440
149 + 33605291 = 33605440
173 + 33605267 = 33605440
233 + 33605207 = 33605440
263 + 33605177 = 33605440

Showing the first eight; more decompositions exist.
