Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33571320, here are decompositions:

17 + 33571303 = 33571320
23 + 33571297 = 33571320
53 + 33571267 = 33571320
67 + 33571253 = 33571320
71 + 33571249 = 33571320
109 + 33571211 = 33571320
157 + 33571163 = 33571320
197 + 33571123 = 33571320

Showing the first eight; more decompositions exist.
