Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487242, here are decompositions:

23 + 33487219 = 33487242
53 + 33487189 = 33487242
79 + 33487163 = 33487242
181 + 33487061 = 33487242
193 + 33487049 = 33487242
211 + 33487031 = 33487242
379 + 33486863 = 33487242
401 + 33486841 = 33487242

Showing the first eight; more decompositions exist.
