Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745200, here are decompositions:

  • 31 + 8745169 = 8745200
  • 67 + 8745133 = 8745200
  • 103 + 8745097 = 8745200
  • 181 + 8745019 = 8745200
  • 271 + 8744929 = 8745200
  • 283 + 8744917 = 8745200
  • 313 + 8744887 = 8745200
  • 367 + 8744833 = 8745200

Showing the first eight; more decompositions exist.
