Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3838, here are decompositions:

  • 5 + 3833 = 3838
  • 17 + 3821 = 3838
  • 41 + 3797 = 3838
  • 59 + 3779 = 3838
  • 71 + 3767 = 3838
  • 137 + 3701 = 3838
  • 167 + 3671 = 3838
  • 179 + 3659 = 3838

Showing the first eight; more decompositions exist.
