Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33490986, here are decompositions:

5 + 33490981 = 33490986
37 + 33490949 = 33490986
59 + 33490927 = 33490986
79 + 33490907 = 33490986
97 + 33490889 = 33490986
173 + 33490813 = 33490986
223 + 33490763 = 33490986
239 + 33490747 = 33490986

Showing the first eight; more decompositions exist.
