Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487898, here are decompositions:

  • 7 + 487891 = 487898
  • 67 + 487831 = 487898
  • 79 + 487819 = 487898
  • 109 + 487789 = 487898
  • 157 + 487741 = 487898
  • 181 + 487717 = 487898
  • 241 + 487657 = 487898
  • 337 + 487561 = 487898

Showing the first eight; more decompositions exist.
