Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557916, here are decompositions:

5 + 33557911 = 33557916
17 + 33557899 = 33557916
23 + 33557893 = 33557916
37 + 33557879 = 33557916
79 + 33557837 = 33557916
89 + 33557827 = 33557916
107 + 33557809 = 33557916
109 + 33557807 = 33557916

Showing the first eight; more decompositions exist.
