Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521964, here are decompositions:

5 + 33521959 = 33521964
11 + 33521953 = 33521964
31 + 33521933 = 33521964
37 + 33521927 = 33521964
43 + 33521921 = 33521964
61 + 33521903 = 33521964
71 + 33521893 = 33521964
101 + 33521863 = 33521964

Showing the first eight; more decompositions exist.
