Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33490868, here are decompositions:

67 + 33490801 = 33490868
241 + 33490627 = 33490868
331 + 33490537 = 33490868
349 + 33490519 = 33490868
487 + 33490381 = 33490868
547 + 33490321 = 33490868
571 + 33490297 = 33490868
661 + 33490207 = 33490868

Showing the first eight; more decompositions exist.
