Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33571278, here are decompositions:

11 + 33571267 = 33571278
29 + 33571249 = 33571278
67 + 33571211 = 33571278
127 + 33571151 = 33571278
157 + 33571121 = 33571278
199 + 33571079 = 33571278
229 + 33571049 = 33571278
241 + 33571037 = 33571278

Showing the first eight; more decompositions exist.
