Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33571538, here are decompositions:

31 + 33571507 = 33571538
151 + 33571387 = 33571538
157 + 33571381 = 33571538
211 + 33571327 = 33571538
241 + 33571297 = 33571538
271 + 33571267 = 33571538
379 + 33571159 = 33571538
541 + 33570997 = 33571538

Showing the first eight; more decompositions exist.
