Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667880, here are decompositions:

  • 17 + 8667863 = 8667880
  • 59 + 8667821 = 8667880
  • 71 + 8667809 = 8667880
  • 83 + 8667797 = 8667880
  • 173 + 8667707 = 8667880
  • 191 + 8667689 = 8667880
  • 227 + 8667653 = 8667880
  • 239 + 8667641 = 8667880

Showing the first eight; more decompositions exist.
