Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33490872, here are decompositions:

29 + 33490843 = 33490872
31 + 33490841 = 33490872
59 + 33490813 = 33490872
71 + 33490801 = 33490872
109 + 33490763 = 33490872
179 + 33490693 = 33490872
269 + 33490603 = 33490872
293 + 33490579 = 33490872

Showing the first eight; more decompositions exist.
