Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33490778, here are decompositions:

31 + 33490747 = 33490778
151 + 33490627 = 33490778
199 + 33490579 = 33490778
241 + 33490537 = 33490778
397 + 33490381 = 33490778
457 + 33490321 = 33490778
499 + 33490279 = 33490778
571 + 33490207 = 33490778

Showing the first eight; more decompositions exist.
