Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718258, here are decompositions:

7 + 8718251 = 8718258
11 + 8718247 = 8718258
37 + 8718221 = 8718258
41 + 8718217 = 8718258
61 + 8718197 = 8718258
67 + 8718191 = 8718258
149 + 8718109 = 8718258
167 + 8718091 = 8718258

Showing the first eight; more decompositions exist.
