Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521772, here are decompositions:

13 + 33521759 = 33521772
19 + 33521753 = 33521772
41 + 33521731 = 33521772
43 + 33521729 = 33521772
59 + 33521713 = 33521772
61 + 33521711 = 33521772
71 + 33521701 = 33521772
79 + 33521693 = 33521772

Showing the first eight; more decompositions exist.
