Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720298, here are decompositions:

17 + 8720281 = 8720298
71 + 8720227 = 8720298
107 + 8720191 = 8720298
109 + 8720189 = 8720298
127 + 8720171 = 8720298
137 + 8720161 = 8720298
179 + 8720119 = 8720298
211 + 8720087 = 8720298

Showing the first eight; more decompositions exist.
