Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33571668, here are decompositions:

5 + 33571663 = 33571668
29 + 33571639 = 33571668
41 + 33571627 = 33571668
59 + 33571609 = 33571668
61 + 33571607 = 33571668
71 + 33571597 = 33571668
181 + 33571487 = 33571668
211 + 33571457 = 33571668

Showing the first eight; more decompositions exist.
