Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33486180, here are decompositions:

17 + 33486163 = 33486180
23 + 33486157 = 33486180
31 + 33486149 = 33486180
37 + 33486143 = 33486180
41 + 33486139 = 33486180
61 + 33486119 = 33486180
71 + 33486109 = 33486180
103 + 33486077 = 33486180

Showing the first eight; more decompositions exist.
