Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31110, here are decompositions:

  • 19 + 31091 = 31110
  • 29 + 31081 = 31110
  • 31 + 31079 = 31110
  • 41 + 31069 = 31110
  • 47 + 31063 = 31110
  • 59 + 31051 = 31110
  • 71 + 31039 = 31110
  • 97 + 31013 = 31110

Showing the first eight; more decompositions exist.
