Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33605620, here are decompositions:

29 + 33605591 = 33605620
53 + 33605567 = 33605620
89 + 33605531 = 33605620
179 + 33605441 = 33605620
227 + 33605393 = 33605620
233 + 33605387 = 33605620
311 + 33605309 = 33605620
353 + 33605267 = 33605620

Showing the first eight; more decompositions exist.
