Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561960, here are decompositions:

7 + 33561953 = 33561960
11 + 33561949 = 33561960
17 + 33561943 = 33561960
31 + 33561929 = 33561960
41 + 33561919 = 33561960
43 + 33561917 = 33561960
79 + 33561881 = 33561960
83 + 33561877 = 33561960

Showing the first eight; more decompositions exist.
