Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33508816, here are decompositions:

83 + 33508733 = 33508816
197 + 33508619 = 33508816
233 + 33508583 = 33508816
239 + 33508577 = 33508816
317 + 33508499 = 33508816
353 + 33508463 = 33508816
773 + 33508043 = 33508816
797 + 33508019 = 33508816

Showing the first eight; more decompositions exist.
