Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727228, here are decompositions:

17 + 8727211 = 8727228
31 + 8727197 = 8727228
67 + 8727161 = 8727228
71 + 8727157 = 8727228
79 + 8727149 = 8727228
109 + 8727119 = 8727228
137 + 8727091 = 8727228
179 + 8727049 = 8727228

Showing the first eight; more decompositions exist.
