Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505808, here are decompositions:

19 + 33505789 = 33505808
31 + 33505777 = 33505808
229 + 33505579 = 33505808
241 + 33505567 = 33505808
367 + 33505441 = 33505808
499 + 33505309 = 33505808
547 + 33505261 = 33505808
631 + 33505177 = 33505808

Showing the first eight; more decompositions exist.
