Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33490960, here are decompositions:

11 + 33490949 = 33490960
53 + 33490907 = 33490960
71 + 33490889 = 33490960
179 + 33490781 = 33490960
197 + 33490763 = 33490960
353 + 33490607 = 33490960
431 + 33490529 = 33490960
563 + 33490397 = 33490960

Showing the first eight; more decompositions exist.
