Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68900, here are decompositions:

  • 3 + 68897 = 68900
  • 19 + 68881 = 68900
  • 37 + 68863 = 68900
  • 79 + 68821 = 68900
  • 109 + 68791 = 68900
  • 151 + 68749 = 68900
  • 157 + 68743 = 68900
  • 163 + 68737 = 68900

Showing the first eight; more decompositions exist.
