Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33571578, here are decompositions:

71 + 33571507 = 33571578
127 + 33571451 = 33571578
191 + 33571387 = 33571578
197 + 33571381 = 33571578
211 + 33571367 = 33571578
251 + 33571327 = 33571578
281 + 33571297 = 33571578
311 + 33571267 = 33571578

Showing the first eight; more decompositions exist.
