Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68904, here are decompositions:

  • 5 + 68899 = 68904
  • 7 + 68897 = 68904
  • 13 + 68891 = 68904
  • 23 + 68881 = 68904
  • 41 + 68863 = 68904
  • 83 + 68821 = 68904
  • 113 + 68791 = 68904
  • 127 + 68777 = 68904

Showing the first eight; more decompositions exist.
