Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33566528, here are decompositions:

31 + 33566497 = 33566528
67 + 33566461 = 33566528
97 + 33566431 = 33566528
109 + 33566419 = 33566528
157 + 33566371 = 33566528
199 + 33566329 = 33566528
271 + 33566257 = 33566528
277 + 33566251 = 33566528

Showing the first eight; more decompositions exist.
