Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33494656, here are decompositions:

23 + 33494633 = 33494656
29 + 33494627 = 33494656
47 + 33494609 = 33494656
137 + 33494519 = 33494656
233 + 33494423 = 33494656
269 + 33494387 = 33494656
347 + 33494309 = 33494656
359 + 33494297 = 33494656

Showing the first eight; more decompositions exist.
