Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3882, here are decompositions:

  • 5 + 3877 = 3882
  • 19 + 3863 = 3882
  • 29 + 3853 = 3882
  • 31 + 3851 = 3882
  • 59 + 3823 = 3882
  • 61 + 3821 = 3882
  • 79 + 3803 = 3882
  • 89 + 3793 = 3882

Showing the first eight; more decompositions exist.
