Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667860, here are decompositions:

  • 13 + 8667847 = 8667860
  • 31 + 8667829 = 8667860
  • 67 + 8667793 = 8667860
  • 127 + 8667733 = 8667860
  • 139 + 8667721 = 8667860
  • 163 + 8667697 = 8667860
  • 199 + 8667661 = 8667860
  • 349 + 8667511 = 8667860

Showing the first eight; more decompositions exist.
