Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521916, here are decompositions:

13 + 33521903 = 33521916
23 + 33521893 = 33521916
53 + 33521863 = 33521916
73 + 33521843 = 33521916
89 + 33521827 = 33521916
157 + 33521759 = 33521916
163 + 33521753 = 33521916
223 + 33521693 = 33521916

Showing the first eight; more decompositions exist.
