Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628288, here are decompositions:

17 + 8628271 = 8628288
101 + 8628187 = 8628288
107 + 8628181 = 8628288
127 + 8628161 = 8628288
131 + 8628157 = 8628288
139 + 8628149 = 8628288
157 + 8628131 = 8628288
167 + 8628121 = 8628288

Showing the first eight; more decompositions exist.
