Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33571644, here are decompositions:

5 + 33571639 = 33571644
11 + 33571633 = 33571644
17 + 33571627 = 33571644
37 + 33571607 = 33571644
47 + 33571597 = 33571644
137 + 33571507 = 33571644
157 + 33571487 = 33571644
181 + 33571463 = 33571644

Showing the first eight; more decompositions exist.
