Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728522, here are decompositions:

  • 41 + 8728481 = 8728522
  • 149 + 8728373 = 8728522
  • 191 + 8728331 = 8728522
  • 233 + 8728289 = 8728522
  • 281 + 8728241 = 8728522
  • 311 + 8728211 = 8728522
  • 353 + 8728169 = 8728522
  • 443 + 8728079 = 8728522

Showing the first eight; more decompositions exist.
