Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727816, here are decompositions:

7 + 8727809 = 8727816
37 + 8727779 = 8727816
43 + 8727773 = 8727816
59 + 8727757 = 8727816
89 + 8727727 = 8727816
127 + 8727689 = 8727816
157 + 8727659 = 8727816
173 + 8727643 = 8727816

Showing the first eight; more decompositions exist.
