Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678864, here are decompositions:

  • 13 + 8678851 = 8678864
  • 31 + 8678833 = 8678864
  • 43 + 8678821 = 8678864
  • 151 + 8678713 = 8678864
  • 157 + 8678707 = 8678864
  • 163 + 8678701 = 8678864
  • 193 + 8678671 = 8678864
  • 277 + 8678587 = 8678864

Showing the first eight; more decompositions exist.
