Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658238, here are decompositions:

5 + 8658233 = 8658238
101 + 8658137 = 8658238
131 + 8658107 = 8658238
137 + 8658101 = 8658238
179 + 8658059 = 8658238
269 + 8657969 = 8658238
311 + 8657927 = 8658238
389 + 8657849 = 8658238

Showing the first eight; more decompositions exist.
