Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998864, here are decompositions:

  • 3 + 998861 = 998864
  • 7 + 998857 = 998864
  • 127 + 998737 = 998864
  • 211 + 998653 = 998864
  • 241 + 998623 = 998864
  • 313 + 998551 = 998864
  • 337 + 998527 = 998864
  • 367 + 998497 = 998864

Showing the first eight; more decompositions exist.
