Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33571638, here are decompositions:

5 + 33571633 = 33571638
11 + 33571627 = 33571638
19 + 33571619 = 33571638
29 + 33571609 = 33571638
31 + 33571607 = 33571638
41 + 33571597 = 33571638
131 + 33571507 = 33571638
151 + 33571487 = 33571638

Showing the first eight; more decompositions exist.
