Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38928, here are decompositions:

  • 5 + 38923 = 38928
  • 7 + 38921 = 38928
  • 11 + 38917 = 38928
  • 37 + 38891 = 38928
  • 61 + 38867 = 38928
  • 67 + 38861 = 38928
  • 89 + 38839 = 38928
  • 107 + 38821 = 38928

Showing the first eight; more decompositions exist.
