Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33605530, here are decompositions:

89 + 33605441 = 33605530
113 + 33605417 = 33605530
137 + 33605393 = 33605530
239 + 33605291 = 33605530
263 + 33605267 = 33605530
311 + 33605219 = 33605530
353 + 33605177 = 33605530
443 + 33605087 = 33605530

Showing the first eight; more decompositions exist.
