Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33490398, here are decompositions:

5 + 33490393 = 33490398
17 + 33490381 = 33490398
37 + 33490361 = 33490398
47 + 33490351 = 33490398
61 + 33490337 = 33490398
101 + 33490297 = 33490398
127 + 33490271 = 33490398
157 + 33490241 = 33490398

Showing the first eight; more decompositions exist.
