Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2104, here are decompositions:

  • 5 + 2099 = 2104
  • 17 + 2087 = 2104
  • 23 + 2081 = 2104
  • 41 + 2063 = 2104
  • 101 + 2003 = 2104
  • 107 + 1997 = 2104
  • 131 + 1973 = 2104
  • 173 + 1931 = 2104

Showing the first eight; more decompositions exist.
