Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666070, here are decompositions:

11 + 8666059 = 8666070
13 + 8666057 = 8666070
19 + 8666051 = 8666070
43 + 8666027 = 8666070
47 + 8666023 = 8666070
53 + 8666017 = 8666070
71 + 8665999 = 8666070
79 + 8665991 = 8666070

Showing the first eight; more decompositions exist.
