Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16864, here are decompositions:

  • 41 + 16823 = 16864
  • 53 + 16811 = 16864
  • 101 + 16763 = 16864
  • 173 + 16691 = 16864
  • 191 + 16673 = 16864
  • 233 + 16631 = 16864
  • 257 + 16607 = 16864
  • 311 + 16553 = 16864

Showing the first eight; more decompositions exist.
