Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33519824, here are decompositions:

31 + 33519793 = 33519824
73 + 33519751 = 33519824
97 + 33519727 = 33519824
181 + 33519643 = 33519824
241 + 33519583 = 33519824
277 + 33519547 = 33519824
367 + 33519457 = 33519824
607 + 33519217 = 33519824

Showing the first eight; more decompositions exist.
