Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727666, here are decompositions:

7 + 8727659 = 8727666
23 + 8727643 = 8727666
43 + 8727623 = 8727666
47 + 8727619 = 8727666
67 + 8727599 = 8727666
83 + 8727583 = 8727666
89 + 8727577 = 8727666
97 + 8727569 = 8727666

Showing the first eight; more decompositions exist.
