Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33486220, here are decompositions:

23 + 33486197 = 33486220
29 + 33486191 = 33486220
41 + 33486179 = 33486220
71 + 33486149 = 33486220
101 + 33486119 = 33486220
149 + 33486071 = 33486220
179 + 33486041 = 33486220
197 + 33486023 = 33486220

Showing the first eight; more decompositions exist.
