Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668020, here are decompositions:

19 + 8668001 = 8668020
41 + 8667979 = 8668020
47 + 8667973 = 8668020
59 + 8667961 = 8668020
71 + 8667949 = 8668020
89 + 8667931 = 8668020
107 + 8667913 = 8668020
113 + 8667907 = 8668020

Showing the first eight; more decompositions exist.
