Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718200, here are decompositions:

  • 3 + 8718197 = 8718200
  • 37 + 8718163 = 8718200
  • 97 + 8718103 = 8718200
  • 103 + 8718097 = 8718200
  • 109 + 8718091 = 8718200
  • 157 + 8718043 = 8718200
  • 193 + 8718007 = 8718200
  • 241 + 8717959 = 8718200

Showing the first eight; more decompositions exist.
