Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3982, here are decompositions:

  • 53 + 3929 = 3982
  • 59 + 3923 = 3982
  • 71 + 3911 = 3982
  • 101 + 3881 = 3982
  • 131 + 3851 = 3982
  • 149 + 3833 = 3982
  • 179 + 3803 = 3982
  • 263 + 3719 = 3982

Showing the first eight; more decompositions exist.
