Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33549568, here are decompositions:

5 + 33549563 = 33549568
11 + 33549557 = 33549568
137 + 33549431 = 33549568
191 + 33549377 = 33549568
257 + 33549311 = 33549568
317 + 33549251 = 33549568
347 + 33549221 = 33549568
431 + 33549137 = 33549568

Showing the first eight; more decompositions exist.
