Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628258, here are decompositions:

71 + 8628187 = 8628258
97 + 8628161 = 8628258
101 + 8628157 = 8628258
109 + 8628149 = 8628258
127 + 8628131 = 8628258
137 + 8628121 = 8628258
151 + 8628107 = 8628258
181 + 8628077 = 8628258

Showing the first eight; more decompositions exist.
