Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33605872, here are decompositions:

23 + 33605849 = 33605872
29 + 33605843 = 33605872
149 + 33605723 = 33605872
281 + 33605591 = 33605872
431 + 33605441 = 33605872
479 + 33605393 = 33605872
563 + 33605309 = 33605872
653 + 33605219 = 33605872

Showing the first eight; more decompositions exist.
