Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19916, here are decompositions:

  • 3 + 19913 = 19916
  • 73 + 19843 = 19916
  • 97 + 19819 = 19916
  • 103 + 19813 = 19916
  • 139 + 19777 = 19916
  • 157 + 19759 = 19916
  • 163 + 19753 = 19916
  • 199 + 19717 = 19916

Showing the first eight; more decompositions exist.
