Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666038, here are decompositions:

11 + 8666027 = 8666038
47 + 8665991 = 8666038
71 + 8665967 = 8666038
89 + 8665949 = 8666038
107 + 8665931 = 8666038
149 + 8665889 = 8666038
239 + 8665799 = 8666038
389 + 8665649 = 8666038

Showing the first eight; more decompositions exist.
