Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505728, here are decompositions:

5 + 33505723 = 33505728
97 + 33505631 = 33505728
107 + 33505621 = 33505728
127 + 33505601 = 33505728
149 + 33505579 = 33505728
181 + 33505547 = 33505728
229 + 33505499 = 33505728
281 + 33505447 = 33505728

Showing the first eight; more decompositions exist.
