Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561790, here are decompositions:

11 + 33561779 = 33561790
23 + 33561767 = 33561790
47 + 33561743 = 33561790
71 + 33561719 = 33561790
137 + 33561653 = 33561790
149 + 33561641 = 33561790
179 + 33561611 = 33561790
191 + 33561599 = 33561790

Showing the first eight; more decompositions exist.
