Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728008, here are decompositions:

  • 19 + 8727989 = 8728008
  • 71 + 8727937 = 8728008
  • 101 + 8727907 = 8728008
  • 109 + 8727899 = 8728008
  • 137 + 8727871 = 8728008
  • 151 + 8727857 = 8728008
  • 199 + 8727809 = 8728008
  • 229 + 8727779 = 8728008

Showing the first eight; more decompositions exist.
