Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505668, here are decompositions:

5 + 33505663 = 33505668
37 + 33505631 = 33505668
47 + 33505621 = 33505668
67 + 33505601 = 33505668
89 + 33505579 = 33505668
101 + 33505567 = 33505668
149 + 33505519 = 33505668
227 + 33505441 = 33505668

Showing the first eight; more decompositions exist.
