Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8607870, here are decompositions:

  • 67 + 8607803 = 8607870
  • 101 + 8607769 = 8607870
  • 137 + 8607733 = 8607870
  • 157 + 8607713 = 8607870
  • 181 + 8607689 = 8607870
  • 197 + 8607673 = 8607870
  • 211 + 8607659 = 8607870
  • 233 + 8607637 = 8607870

Showing the first eight; more decompositions exist.
