Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3910, here are decompositions:

  • 3 + 3907 = 3910
  • 29 + 3881 = 3910
  • 47 + 3863 = 3910
  • 59 + 3851 = 3910
  • 89 + 3821 = 3910
  • 107 + 3803 = 3910
  • 113 + 3797 = 3910
  • 131 + 3779 = 3910

Showing the first eight; more decompositions exist.
