Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33571990, here are decompositions:

47 + 33571943 = 33571990
59 + 33571931 = 33571990
167 + 33571823 = 33571990
173 + 33571817 = 33571990
197 + 33571793 = 33571990
251 + 33571739 = 33571990
269 + 33571721 = 33571990
281 + 33571709 = 33571990

Showing the first eight; more decompositions exist.
