Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727656, here are decompositions:

13 + 8727643 = 8727656
37 + 8727619 = 8727656
73 + 8727583 = 8727656
79 + 8727577 = 8727656
127 + 8727529 = 8727656
163 + 8727493 = 8727656
229 + 8727427 = 8727656
307 + 8727349 = 8727656

Showing the first eight; more decompositions exist.
