Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505918, here are decompositions:

11 + 33505907 = 33505918
29 + 33505889 = 33505918
59 + 33505859 = 33505918
71 + 33505847 = 33505918
137 + 33505781 = 33505918
167 + 33505751 = 33505918
317 + 33505601 = 33505918
419 + 33505499 = 33505918

Showing the first eight; more decompositions exist.
