Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712066, here are decompositions:

7 + 8712059 = 8712066
37 + 8712029 = 8712066
47 + 8712019 = 8712066
79 + 8711987 = 8712066
113 + 8711953 = 8712066
179 + 8711887 = 8712066
197 + 8711869 = 8712066
199 + 8711867 = 8712066

Showing the first eight; more decompositions exist.
