Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20146, here are decompositions:

  • 3 + 20143 = 20146
  • 17 + 20129 = 20146
  • 23 + 20123 = 20146
  • 29 + 20117 = 20146
  • 83 + 20063 = 20146
  • 149 + 19997 = 20146
  • 167 + 19979 = 20146
  • 173 + 19973 = 20146

Showing the first eight; more decompositions exist.
