Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91986, here are decompositions:

  • 17 + 91969 = 91986
  • 19 + 91967 = 91986
  • 29 + 91957 = 91986
  • 43 + 91943 = 91986
  • 47 + 91939 = 91986
  • 113 + 91873 = 91986
  • 149 + 91837 = 91986
  • 163 + 91823 = 91986

Showing the first eight; more decompositions exist.
