Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33571972, here are decompositions:

29 + 33571943 = 33571972
41 + 33571931 = 33571972
149 + 33571823 = 33571972
179 + 33571793 = 33571972
233 + 33571739 = 33571972
251 + 33571721 = 33571972
263 + 33571709 = 33571972
353 + 33571619 = 33571972

Showing the first eight; more decompositions exist.
