Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751320, here are decompositions:

  • 31 + 8751289 = 8751320
  • 139 + 8751181 = 8751320
  • 163 + 8751157 = 8751320
  • 181 + 8751139 = 8751320
  • 223 + 8751097 = 8751320
  • 229 + 8751091 = 8751320
  • 241 + 8751079 = 8751320
  • 283 + 8751037 = 8751320

Showing the first eight; more decompositions exist.
