Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33486218, here are decompositions:

19 + 33486199 = 33486218
61 + 33486157 = 33486218
79 + 33486139 = 33486218
109 + 33486109 = 33486218
211 + 33486007 = 33486218
229 + 33485989 = 33486218
277 + 33485941 = 33486218
331 + 33485887 = 33486218

Showing the first eight; more decompositions exist.
