Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513538, here are decompositions:

5 + 33513533 = 33513538
29 + 33513509 = 33513538
59 + 33513479 = 33513538
131 + 33513407 = 33513538
137 + 33513401 = 33513538
257 + 33513281 = 33513538
281 + 33513257 = 33513538
431 + 33513107 = 33513538

Showing the first eight; more decompositions exist.
