Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33504640, here are decompositions:

23 + 33504617 = 33504640
83 + 33504557 = 33504640
89 + 33504551 = 33504640
263 + 33504377 = 33504640
293 + 33504347 = 33504640
311 + 33504329 = 33504640
347 + 33504293 = 33504640
353 + 33504287 = 33504640

Showing the first eight; more decompositions exist.
