Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658370, here are decompositions:

41 + 8658329 = 8658370
47 + 8658323 = 8658370
137 + 8658233 = 8658370
167 + 8658203 = 8658370
233 + 8658137 = 8658370
263 + 8658107 = 8658370
269 + 8658101 = 8658370
311 + 8658059 = 8658370

Showing the first eight; more decompositions exist.
