Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2146, here are decompositions:

  • 3 + 2143 = 2146
  • 5 + 2141 = 2146
  • 17 + 2129 = 2146
  • 47 + 2099 = 2146
  • 59 + 2087 = 2146
  • 83 + 2063 = 2146
  • 107 + 2039 = 2146
  • 149 + 1997 = 2146

Showing the first eight; more decompositions exist.
