Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513568, here are decompositions:

17 + 33513551 = 33513568
29 + 33513539 = 33513568
59 + 33513509 = 33513568
89 + 33513479 = 33513568
167 + 33513401 = 33513568
311 + 33513257 = 33513568
401 + 33513167 = 33513568
461 + 33513107 = 33513568

Showing the first eight; more decompositions exist.
