Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658258, here are decompositions:

41 + 8658217 = 8658258
97 + 8658161 = 8658258
149 + 8658109 = 8658258
151 + 8658107 = 8658258
157 + 8658101 = 8658258
199 + 8658059 = 8658258
241 + 8658017 = 8658258
331 + 8657927 = 8658258

Showing the first eight; more decompositions exist.
