Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40068, here are decompositions:

  • 5 + 40063 = 40068
  • 29 + 40039 = 40068
  • 31 + 40037 = 40068
  • 37 + 40031 = 40068
  • 59 + 40009 = 40068
  • 79 + 39989 = 40068
  • 89 + 39979 = 40068
  • 97 + 39971 = 40068

Showing the first eight; more decompositions exist.
