Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521152, here are decompositions:

11 + 33521141 = 33521152
53 + 33521099 = 33521152
113 + 33521039 = 33521152
131 + 33521021 = 33521152
149 + 33521003 = 33521152
173 + 33520979 = 33521152
179 + 33520973 = 33521152
233 + 33520919 = 33521152

Showing the first eight; more decompositions exist.
