Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561768, here are decompositions:

17 + 33561751 = 33561768
89 + 33561679 = 33561768
127 + 33561641 = 33561768
157 + 33561611 = 33561768
197 + 33561571 = 33561768
211 + 33561557 = 33561768
241 + 33561527 = 33561768
379 + 33561389 = 33561768

Showing the first eight; more decompositions exist.
