Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561980, here are decompositions:

3 + 33561977 = 33561980
31 + 33561949 = 33561980
37 + 33561943 = 33561980
61 + 33561919 = 33561980
103 + 33561877 = 33561980
163 + 33561817 = 33561980
181 + 33561799 = 33561980
211 + 33561769 = 33561980

Showing the first eight; more decompositions exist.
