Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581268, here are decompositions:

5 + 33581263 = 33581268
11 + 33581257 = 33581268
47 + 33581221 = 33581268
59 + 33581209 = 33581268
137 + 33581131 = 33581268
151 + 33581117 = 33581268
181 + 33581087 = 33581268
241 + 33581027 = 33581268

Showing the first eight; more decompositions exist.
