Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67868, here are decompositions:

  • 61 + 67807 = 67868
  • 67 + 67801 = 67868
  • 79 + 67789 = 67868
  • 109 + 67759 = 67868
  • 127 + 67741 = 67868
  • 331 + 67537 = 67868
  • 337 + 67531 = 67868
  • 379 + 67489 = 67868

Showing the first eight; more decompositions exist.
