Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666850, here are decompositions:

  • 11 + 8666839 = 8666850
  • 41 + 8666809 = 8666850
  • 43 + 8666807 = 8666850
  • 53 + 8666797 = 8666850
  • 67 + 8666783 = 8666850
  • 83 + 8666767 = 8666850
  • 103 + 8666747 = 8666850
  • 139 + 8666711 = 8666850

Showing the first eight; more decompositions exist.
