Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505784, here are decompositions:

3 + 33505781 = 33505784
7 + 33505777 = 33505784
61 + 33505723 = 33505784
163 + 33505621 = 33505784
211 + 33505573 = 33505784
241 + 33505543 = 33505784
337 + 33505447 = 33505784
421 + 33505363 = 33505784

Showing the first eight; more decompositions exist.
