Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669400, here are decompositions:

  • 7 + 8669393 = 8669400
  • 11 + 8669389 = 8669400
  • 59 + 8669341 = 8669400
  • 67 + 8669333 = 8669400
  • 71 + 8669329 = 8669400
  • 83 + 8669317 = 8669400
  • 107 + 8669293 = 8669400
  • 149 + 8669251 = 8669400

Showing the first eight; more decompositions exist.
