Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531668, here are decompositions:

7 + 33531661 = 33531668
109 + 33531559 = 33531668
127 + 33531541 = 33531668
199 + 33531469 = 33531668
229 + 33531439 = 33531668
241 + 33531427 = 33531668
271 + 33531397 = 33531668
277 + 33531391 = 33531668

Showing the first eight; more decompositions exist.
