Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521328, here are decompositions:

7 + 33521321 = 33521328
107 + 33521221 = 33521328
109 + 33521219 = 33521328
149 + 33521179 = 33521328
151 + 33521177 = 33521328
157 + 33521171 = 33521328
229 + 33521099 = 33521328
241 + 33521087 = 33521328

Showing the first eight; more decompositions exist.
