Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33571440, here are decompositions:

47 + 33571393 = 33571440
53 + 33571387 = 33571440
59 + 33571381 = 33571440
73 + 33571367 = 33571440
113 + 33571327 = 33571440
137 + 33571303 = 33571440
173 + 33571267 = 33571440
191 + 33571249 = 33571440

Showing the first eight; more decompositions exist.
