Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3828, here are decompositions:

  • 5 + 3823 = 3828
  • 7 + 3821 = 3828
  • 31 + 3797 = 3828
  • 59 + 3769 = 3828
  • 61 + 3767 = 3828
  • 67 + 3761 = 3828
  • 89 + 3739 = 3828
  • 101 + 3727 = 3828

Showing the first eight; more decompositions exist.
