Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715258, here are decompositions:

67 + 8715191 = 8715258
107 + 8715151 = 8715258
151 + 8715107 = 8715258
179 + 8715079 = 8715258
199 + 8715059 = 8715258
229 + 8715029 = 8715258
239 + 8715019 = 8715258
269 + 8714989 = 8715258

Showing the first eight; more decompositions exist.
