Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709860, here are decompositions:

  • 43 + 8709817 = 8709860
  • 67 + 8709793 = 8709860
  • 79 + 8709781 = 8709860
  • 109 + 8709751 = 8709860
  • 139 + 8709721 = 8709860
  • 163 + 8709697 = 8709860
  • 307 + 8709553 = 8709860
  • 487 + 8709373 = 8709860

Showing the first eight; more decompositions exist.
