Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33523280, here are decompositions:

19 + 33523261 = 33523280
61 + 33523219 = 33523280
139 + 33523141 = 33523280
277 + 33523003 = 33523280
367 + 33522913 = 33523280
379 + 33522901 = 33523280
541 + 33522739 = 33523280
709 + 33522571 = 33523280

Showing the first eight; more decompositions exist.
