Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33486018, here are decompositions:

11 + 33486007 = 33486018
17 + 33486001 = 33486018
29 + 33485989 = 33486018
61 + 33485957 = 33486018
79 + 33485939 = 33486018
109 + 33485909 = 33486018
127 + 33485891 = 33486018
131 + 33485887 = 33486018

Showing the first eight; more decompositions exist.
