Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658138, here are decompositions:

29 + 8658109 = 8658138
31 + 8658107 = 8658138
37 + 8658101 = 8658138
79 + 8658059 = 8658138
211 + 8657927 = 8658138
257 + 8657881 = 8658138
311 + 8657827 = 8658138
337 + 8657801 = 8658138

Showing the first eight; more decompositions exist.
