Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76800, here are decompositions:

  • 19 + 76781 = 76800
  • 23 + 76777 = 76800
  • 29 + 76771 = 76800
  • 43 + 76757 = 76800
  • 47 + 76753 = 76800
  • 67 + 76733 = 76800
  • 83 + 76717 = 76800
  • 103 + 76697 = 76800

Showing the first eight; more decompositions exist.
