Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33498640, here are decompositions:

11 + 33498629 = 33498640
17 + 33498623 = 33498640
137 + 33498503 = 33498640
167 + 33498473 = 33498640
173 + 33498467 = 33498640
179 + 33498461 = 33498640
233 + 33498407 = 33498640
239 + 33498401 = 33498640

Showing the first eight; more decompositions exist.
