Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33511808, here are decompositions:

19 + 33511789 = 33511808
79 + 33511729 = 33511808
139 + 33511669 = 33511808
181 + 33511627 = 33511808
199 + 33511609 = 33511808
277 + 33511531 = 33511808
409 + 33511399 = 33511808
487 + 33511321 = 33511808

Showing the first eight; more decompositions exist.
