Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33571428, here are decompositions:

41 + 33571387 = 33571428
47 + 33571381 = 33571428
61 + 33571367 = 33571428
101 + 33571327 = 33571428
131 + 33571297 = 33571428
179 + 33571249 = 33571428
269 + 33571159 = 33571428
277 + 33571151 = 33571428

Showing the first eight; more decompositions exist.
