Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33519920, here are decompositions:

13 + 33519907 = 33519920
43 + 33519877 = 33519920
127 + 33519793 = 33519920
151 + 33519769 = 33519920
193 + 33519727 = 33519920
211 + 33519709 = 33519920
277 + 33519643 = 33519920
331 + 33519589 = 33519920

Showing the first eight; more decompositions exist.
