Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660006, here are decompositions:

7 + 8659999 = 8660006
67 + 8659939 = 8660006
79 + 8659927 = 8660006
97 + 8659909 = 8660006
139 + 8659867 = 8660006
337 + 8659669 = 8660006
379 + 8659627 = 8660006
463 + 8659543 = 8660006

Showing the first eight; more decompositions exist.
