Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33571978, here are decompositions:

47 + 33571931 = 33571978
149 + 33571829 = 33571978
239 + 33571739 = 33571978
257 + 33571721 = 33571978
269 + 33571709 = 33571978
359 + 33571619 = 33571978
491 + 33571487 = 33571978
521 + 33571457 = 33571978

Showing the first eight; more decompositions exist.
