Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505812, here are decompositions:

13 + 33505799 = 33505812
23 + 33505789 = 33505812
31 + 33505781 = 33505812
61 + 33505751 = 33505812
89 + 33505723 = 33505812
149 + 33505663 = 33505812
181 + 33505631 = 33505812
191 + 33505621 = 33505812

Showing the first eight; more decompositions exist.
