Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513550, here are decompositions:

3 + 33513547 = 33513550
11 + 33513539 = 33513550
17 + 33513533 = 33513550
41 + 33513509 = 33513550
47 + 33513503 = 33513550
71 + 33513479 = 33513550
149 + 33513401 = 33513550
269 + 33513281 = 33513550

Showing the first eight; more decompositions exist.
