Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521976, here are decompositions:

17 + 33521959 = 33521976
23 + 33521953 = 33521976
43 + 33521933 = 33521976
73 + 33521903 = 33521976
83 + 33521893 = 33521976
113 + 33521863 = 33521976
149 + 33521827 = 33521976
179 + 33521797 = 33521976

Showing the first eight; more decompositions exist.
