Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561816, here are decompositions:

17 + 33561799 = 33561816
37 + 33561779 = 33561816
47 + 33561769 = 33561816
73 + 33561743 = 33561816
97 + 33561719 = 33561816
137 + 33561679 = 33561816
163 + 33561653 = 33561816
257 + 33561559 = 33561816

Showing the first eight; more decompositions exist.
