Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43878, here are decompositions:

  • 11 + 43867 = 43878
  • 89 + 43789 = 43878
  • 97 + 43781 = 43878
  • 101 + 43777 = 43878
  • 157 + 43721 = 43878
  • 167 + 43711 = 43878
  • 227 + 43651 = 43878
  • 229 + 43649 = 43878

Showing the first eight; more decompositions exist.
