Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33549540, here are decompositions:

29 + 33549511 = 33549540
109 + 33549431 = 33549540
113 + 33549427 = 33549540
137 + 33549403 = 33549540
163 + 33549377 = 33549540
181 + 33549359 = 33549540
191 + 33549349 = 33549540
229 + 33549311 = 33549540

Showing the first eight; more decompositions exist.
