Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664772, here are decompositions:

  • 29 + 8664743 = 8664772
  • 41 + 8664731 = 8664772
  • 71 + 8664701 = 8664772
  • 101 + 8664671 = 8664772
  • 191 + 8664581 = 8664772
  • 353 + 8664419 = 8664772
  • 359 + 8664413 = 8664772
  • 383 + 8664389 = 8664772

Showing the first eight; more decompositions exist.
