Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33569920, here are decompositions:

11 + 33569909 = 33569920
101 + 33569819 = 33569920
107 + 33569813 = 33569920
149 + 33569771 = 33569920
179 + 33569741 = 33569920
191 + 33569729 = 33569920
317 + 33569603 = 33569920
347 + 33569573 = 33569920

Showing the first eight; more decompositions exist.
