Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10200, here are decompositions:

  • 7 + 10193 = 10200
  • 19 + 10181 = 10200
  • 23 + 10177 = 10200
  • 31 + 10169 = 10200
  • 37 + 10163 = 10200
  • 41 + 10159 = 10200
  • 59 + 10141 = 10200
  • 61 + 10139 = 10200

Showing the first eight; more decompositions exist.
