Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513520, here are decompositions:

11 + 33513509 = 33513520
17 + 33513503 = 33513520
41 + 33513479 = 33513520
113 + 33513407 = 33513520
239 + 33513281 = 33513520
263 + 33513257 = 33513520
317 + 33513203 = 33513520
353 + 33513167 = 33513520

Showing the first eight; more decompositions exist.
