Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33571520, here are decompositions:

13 + 33571507 = 33571520
67 + 33571453 = 33571520
127 + 33571393 = 33571520
139 + 33571381 = 33571520
193 + 33571327 = 33571520
223 + 33571297 = 33571520
271 + 33571249 = 33571520
397 + 33571123 = 33571520

Showing the first eight; more decompositions exist.
