Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33506840, here are decompositions:

19 + 33506821 = 33506840
43 + 33506797 = 33506840
67 + 33506773 = 33506840
151 + 33506689 = 33506840
181 + 33506659 = 33506840
223 + 33506617 = 33506840
271 + 33506569 = 33506840
277 + 33506563 = 33506840

Showing the first eight; more decompositions exist.
