Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631258, here are decompositions:

7 + 8631251 = 8631258
11 + 8631247 = 8631258
29 + 8631229 = 8631258
59 + 8631199 = 8631258
67 + 8631191 = 8631258
107 + 8631151 = 8631258
149 + 8631109 = 8631258
241 + 8631017 = 8631258

Showing the first eight; more decompositions exist.
