Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505810, here are decompositions:

11 + 33505799 = 33505810
29 + 33505781 = 33505810
59 + 33505751 = 33505810
179 + 33505631 = 33505810
263 + 33505547 = 33505810
311 + 33505499 = 33505810
449 + 33505361 = 33505810
509 + 33505301 = 33505810

Showing the first eight; more decompositions exist.
