Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727216, here are decompositions:

5 + 8727211 = 8727216
19 + 8727197 = 8727216
37 + 8727179 = 8727216
53 + 8727163 = 8727216
59 + 8727157 = 8727216
67 + 8727149 = 8727216
97 + 8727119 = 8727216
103 + 8727113 = 8727216

Showing the first eight; more decompositions exist.
