Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72898, here are decompositions:

  • 5 + 72893 = 72898
  • 29 + 72869 = 72898
  • 101 + 72797 = 72898
  • 131 + 72767 = 72898
  • 179 + 72719 = 72898
  • 191 + 72707 = 72898
  • 197 + 72701 = 72898
  • 227 + 72671 = 72898

Showing the first eight; more decompositions exist.
