Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28146, here are decompositions:

  • 23 + 28123 = 28146
  • 37 + 28109 = 28146
  • 47 + 28099 = 28146
  • 59 + 28087 = 28146
  • 89 + 28057 = 28146
  • 127 + 28019 = 28146
  • 149 + 27997 = 28146
  • 163 + 27983 = 28146

Showing the first eight; more decompositions exist.
