Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678790, here are decompositions:

  • 7 + 8678783 = 8678790
  • 11 + 8678779 = 8678790
  • 13 + 8678777 = 8678790
  • 17 + 8678773 = 8678790
  • 31 + 8678759 = 8678790
  • 37 + 8678753 = 8678790
  • 41 + 8678749 = 8678790
  • 83 + 8678707 = 8678790

Showing the first eight; more decompositions exist.
