Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707830, here are decompositions:

  • 13 + 8707817 = 8707830
  • 37 + 8707793 = 8707830
  • 67 + 8707763 = 8707830
  • 83 + 8707747 = 8707830
  • 179 + 8707651 = 8707830
  • 181 + 8707649 = 8707830
  • 199 + 8707631 = 8707830
  • 223 + 8707607 = 8707830

Showing the first eight; more decompositions exist.
