Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33490978, here are decompositions:

29 + 33490949 = 33490978
71 + 33490907 = 33490978
89 + 33490889 = 33490978
137 + 33490841 = 33490978
197 + 33490781 = 33490978
431 + 33490547 = 33490978
449 + 33490529 = 33490978
569 + 33490409 = 33490978

Showing the first eight; more decompositions exist.
