Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557904, here are decompositions:

5 + 33557899 = 33557904
11 + 33557893 = 33557904
13 + 33557891 = 33557904
67 + 33557837 = 33557904
97 + 33557807 = 33557904
137 + 33557767 = 33557904
151 + 33557753 = 33557904
167 + 33557737 = 33557904

Showing the first eight; more decompositions exist.
