Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33508280, here are decompositions:

19 + 33508261 = 33508280
61 + 33508219 = 33508280
67 + 33508213 = 33508280
97 + 33508183 = 33508280
367 + 33507913 = 33508280
373 + 33507907 = 33508280
499 + 33507781 = 33508280
601 + 33507679 = 33508280

Showing the first eight; more decompositions exist.
