Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678782, here are decompositions:

  • 3 + 8678779 = 8678782
  • 5 + 8678777 = 8678782
  • 23 + 8678759 = 8678782
  • 29 + 8678753 = 8678782
  • 41 + 8678741 = 8678782
  • 83 + 8678699 = 8678782
  • 89 + 8678693 = 8678782
  • 113 + 8678669 = 8678782

Showing the first eight; more decompositions exist.
