Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33571912, here are decompositions:

83 + 33571829 = 33571912
89 + 33571823 = 33571912
173 + 33571739 = 33571912
191 + 33571721 = 33571912
293 + 33571619 = 33571912
389 + 33571523 = 33571912
449 + 33571463 = 33571912
461 + 33571451 = 33571912

Showing the first eight; more decompositions exist.
