Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33519808, here are decompositions:

17 + 33519791 = 33519808
59 + 33519749 = 33519808
149 + 33519659 = 33519808
191 + 33519617 = 33519808
269 + 33519539 = 33519808
281 + 33519527 = 33519808
359 + 33519449 = 33519808
389 + 33519419 = 33519808

Showing the first eight; more decompositions exist.
