Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33490990, here are decompositions:

3 + 33490987 = 33490990
41 + 33490949 = 33490990
83 + 33490907 = 33490990
101 + 33490889 = 33490990
149 + 33490841 = 33490990
173 + 33490817 = 33490990
227 + 33490763 = 33490990
353 + 33490637 = 33490990

Showing the first eight; more decompositions exist.
