Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521900, here are decompositions:

7 + 33521893 = 33521900
37 + 33521863 = 33521900
73 + 33521827 = 33521900
79 + 33521821 = 33521900
103 + 33521797 = 33521900
199 + 33521701 = 33521900
211 + 33521689 = 33521900
271 + 33521629 = 33521900

Showing the first eight; more decompositions exist.
