Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33490400, here are decompositions:

3 + 33490397 = 33490400
7 + 33490393 = 33490400
19 + 33490381 = 33490400
79 + 33490321 = 33490400
103 + 33490297 = 33490400
193 + 33490207 = 33490400
199 + 33490201 = 33490400
211 + 33490189 = 33490400

Showing the first eight; more decompositions exist.
