Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33605868, here are decompositions:

5 + 33605863 = 33605868
19 + 33605849 = 33605868
29 + 33605839 = 33605868
31 + 33605837 = 33605868
61 + 33605807 = 33605868
71 + 33605797 = 33605868
139 + 33605729 = 33605868
151 + 33605717 = 33605868

Showing the first eight; more decompositions exist.
