Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33620840, here are decompositions:

31 + 33620809 = 33620840
37 + 33620803 = 33620840
73 + 33620767 = 33620840
79 + 33620761 = 33620840
151 + 33620689 = 33620840
181 + 33620659 = 33620840
223 + 33620617 = 33620840
277 + 33620563 = 33620840

Showing the first eight; more decompositions exist.
