Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678868, here are decompositions:

  • 5 + 8678863 = 8678868
  • 17 + 8678851 = 8678868
  • 47 + 8678821 = 8678868
  • 89 + 8678779 = 8678868
  • 109 + 8678759 = 8678868
  • 127 + 8678741 = 8678868
  • 167 + 8678701 = 8678868
  • 197 + 8678671 = 8678868

Showing the first eight; more decompositions exist.
