Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71982, here are decompositions:

  • 11 + 71971 = 71982
  • 19 + 71963 = 71982
  • 41 + 71941 = 71982
  • 73 + 71909 = 71982
  • 83 + 71899 = 71982
  • 101 + 71881 = 71982
  • 103 + 71879 = 71982
  • 139 + 71843 = 71982

Showing the first eight; more decompositions exist.
