Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667858, here are decompositions:

  • 11 + 8667847 = 8667858
  • 29 + 8667829 = 8667858
  • 37 + 8667821 = 8667858
  • 61 + 8667797 = 8667858
  • 131 + 8667727 = 8667858
  • 137 + 8667721 = 8667858
  • 151 + 8667707 = 8667858
  • 181 + 8667677 = 8667858

Showing the first eight; more decompositions exist.
