Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557540, here are decompositions:

19 + 33557521 = 33557540
31 + 33557509 = 33557540
73 + 33557467 = 33557540
127 + 33557413 = 33557540
199 + 33557341 = 33557540
223 + 33557317 = 33557540
283 + 33557257 = 33557540
337 + 33557203 = 33557540

Showing the first eight; more decompositions exist.
