Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561966, here are decompositions:

7 + 33561959 = 33561966
13 + 33561953 = 33561966
17 + 33561949 = 33561966
23 + 33561943 = 33561966
37 + 33561929 = 33561966
47 + 33561919 = 33561966
89 + 33561877 = 33561966
127 + 33561839 = 33561966

Showing the first eight; more decompositions exist.
