Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33490640, here are decompositions:

3 + 33490637 = 33490640
13 + 33490627 = 33490640
37 + 33490603 = 33490640
61 + 33490579 = 33490640
67 + 33490573 = 33490640
103 + 33490537 = 33490640
163 + 33490477 = 33490640
433 + 33490207 = 33490640

Showing the first eight; more decompositions exist.
