Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728006, here are decompositions:

  • 17 + 8727989 = 8728006
  • 107 + 8727899 = 8728006
  • 149 + 8727857 = 8728006
  • 197 + 8727809 = 8728006
  • 227 + 8727779 = 8728006
  • 233 + 8727773 = 8728006
  • 239 + 8727767 = 8728006
  • 317 + 8727689 = 8728006

Showing the first eight; more decompositions exist.
