Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521986, here are decompositions:

5 + 33521981 = 33521986
53 + 33521933 = 33521986
59 + 33521927 = 33521986
83 + 33521903 = 33521986
227 + 33521759 = 33521986
233 + 33521753 = 33521986
257 + 33521729 = 33521986
293 + 33521693 = 33521986

Showing the first eight; more decompositions exist.
