Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33519816, here are decompositions:

23 + 33519793 = 33519816
47 + 33519769 = 33519816
67 + 33519749 = 33519816
89 + 33519727 = 33519816
107 + 33519709 = 33519816
157 + 33519659 = 33519816
173 + 33519643 = 33519816
193 + 33519623 = 33519816

Showing the first eight; more decompositions exist.
