Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3938, here are decompositions:

  • 7 + 3931 = 3938
  • 19 + 3919 = 3938
  • 31 + 3907 = 3938
  • 61 + 3877 = 3938
  • 199 + 3739 = 3938
  • 211 + 3727 = 3938
  • 229 + 3709 = 3938
  • 241 + 3697 = 3938

Showing the first eight; more decompositions exist.
