Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709200, here are decompositions:

  • 13 + 8709187 = 8709200
  • 61 + 8709139 = 8709200
  • 67 + 8709133 = 8709200
  • 79 + 8709121 = 8709200
  • 193 + 8709007 = 8709200
  • 229 + 8708971 = 8709200
  • 307 + 8708893 = 8709200
  • 397 + 8708803 = 8709200

Showing the first eight; more decompositions exist.
