Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33605988, here are decompositions:

7 + 33605981 = 33605988
19 + 33605969 = 33605988
29 + 33605959 = 33605988
107 + 33605881 = 33605988
139 + 33605849 = 33605988
149 + 33605839 = 33605988
151 + 33605837 = 33605988
181 + 33605807 = 33605988

Showing the first eight; more decompositions exist.
