Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689878, here are decompositions:

  • 37 + 8689841 = 8689878
  • 61 + 8689817 = 8689878
  • 79 + 8689799 = 8689878
  • 101 + 8689777 = 8689878
  • 149 + 8689729 = 8689878
  • 151 + 8689727 = 8689878
  • 167 + 8689711 = 8689878
  • 191 + 8689687 = 8689878

Showing the first eight; more decompositions exist.
