Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009216, here are decompositions:

17 + 1009199 = 1009216
23 + 1009193 = 1009216
53 + 1009163 = 1009216
59 + 1009157 = 1009216
167 + 1009049 = 1009216
179 + 1009037 = 1009216
227 + 1008989 = 1009216
233 + 1008983 = 1009216

Showing the first eight; more decompositions exist.
