Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027216, here are decompositions:

5 + 1027211 = 1027216
17 + 1027199 = 1027216
53 + 1027163 = 1027216
89 + 1027127 = 1027216
149 + 1027067 = 1027216
227 + 1026989 = 1027216
269 + 1026947 = 1027216
317 + 1026899 = 1027216

Showing the first eight; more decompositions exist.
