Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33486388, here are decompositions:

17 + 33486371 = 33486388
107 + 33486281 = 33486388
137 + 33486251 = 33486388
191 + 33486197 = 33486388
197 + 33486191 = 33486388
239 + 33486149 = 33486388
269 + 33486119 = 33486388
311 + 33486077 = 33486388

Showing the first eight; more decompositions exist.
